10-point Terminal Models
Note: The
10-point model has a normal
I/O delay time of 19.2 m (typical); 10-point models with short I/O delay time are not available.
The transmission signals of the 16-point PLC connector model are not compatible with those of the 10-point model. Therefore
16-point
PLC connector models and 10-point models cannot be used in combination.

More economical than previous multipoint trans-
mission terminals.
Transmit 16 input signals over just 2 wires (or 3
wires if only one Terminal has power supply.)
Models available with normal I/O delay time
(19.2 ms typical) or short I/O delay time (3 ms
typical).
Models
available with the HOLD function or LOAD
OFF function for processing transmission errors.
A series of B7AS models as compact as 10-point
screw terminal models are available.

VCTF
cable is used, however
, the transmission distance will be 10 m maximum regardless of whether or not independent power
supplies
for the Input and the Output Link T
erminals are used.
3.
The minimum input time is required for the B7A/B7AS to read an input signal.
4.
For high-speed models, these values are possible without grounding the shielded line.

2. The
transmission distance values stated in this table are possible if the Input or Output Link T
erminal is connected to an independent
power
supply
. If a single power supply is connected to the Input or Output Link T
erminal, the supply voltage must be 24 VDC
±10%,
in which case the transmission distance of a normal-speed model is 100 m maximum and that of a high-speed model is 50 m maxi
-
mum.
Refer to
Power Supply
on page
36 for details.
3. A
shielded transmission cable or a VCTF cable with a thickness of
0.75 mm

minimum must be used for signal transmission. If the
VCTF
cable is used, however
, the transmission distance will be 10 m maximum regardless of whether or not independent power
supplies
for the Input and the Output Link T
erminals are used.
4.
The minimum input time is required for the B7A to read an input signal.
5.
Set the timer of the PLC to 0.02 s minimum if a normal-speed model is connected to the PLC.
6.
For high-speed models, these values are possible without grounding the shielded line.

Precautions
General
Electric Shock
Do not touch charged parts of relay terminals or socket terminals
while
power is supplied. Doing so may result in electric shock.
Wiring
Be sure to turn the power OFF before performing wiring. Do not
touch
the terminal block while power is supplied unless the cover is
mounted.
Doing so may result in electric shock.
Be
sure to apply the
specified voltage to input terminals. Applying an
incorrect voltage may prevent the product from operating with its
rated
performance
characteristics, or may cause damage or burn
-
ing.
Relay
Models
Do not use the product for loads that exceed the rated values for
switching
capacity (e.g., switching
voltage and switching current). If
the ratings are exceeded the product may not be able to operate
with its rated performance characteristics due to factors such as
insulation failure, contact failure, or contact welding. It may even
result
in damage to or burning of the relay
.
The lifetime of relays varies significantly with the switching condi-
tions. Be sure to confirm the required performance characteristics
by
testing the relay
under actual operating conditions, and use the
relay
at a frequency at which it can perform with the required perfor
-
mance
characteristics. Continued use of the relay in a state where
it
cannot maintain the rated characteristics may eventually result in
damage
to the insulation between circuits or burning of the relay
.
Do not use the product in locations subject to flammable or
explo
-
sive
gases. Doing
so may result in fire or explosion due to the arcing
that accompanies the switching mechanism and heating
up of the
relay.
No-contact Output (Transistor
, Power MOS FET Relay
, and
SSR Output)
Do not use the product for loads that exceed the rated output cur
-
rent.
Doing so may damage output elements and result in short-cir
-
cuiting
or open circuits.
When
using the product for DC inductive loads, connect a diode
that
will
prevent reverse voltages. Not doing so may damage output ele
-
ments
and result in short-circuiting or open circuits.
Correct Use
Link
T
erminals with Relay Outputs
This Link T
erminal is for relay output.
G70D-R6Rj1-B7A Link Terminals use 24-VDC G6D-1A Relays
and
G70D-R6M
j
1-B7A Link T
erminals use 24-VDC G3DZ-2R6PL
Relays.
When replacing relays, use the yellow Relay Removal Tool at the
corner
of the screw terminal (except for G7TC).
Do not mount or dismount relays with the power supplied.
Opening the Front Cover (Rotating T
ype):
Hold
the two bottom corners of the front cover
(labelled A in the dia
-
gram

Replacing Relays
Do
not mount or dismount relays with the power supplied. Doing so
may
result in electric shock or malfunction.
When replacing relays, use the yellow Relay Removal Tool at the
corner
of the screw terminal (except for G7TC).
Relays
must be inserted
vertically so that the legs do not bend. Not
inserting
relays properly may result in malfunction or heating.
Wiring
Be
sure that terminal polarity
, wiring between the transmission lines
and
power supply
, and the voltage
specifications for I/O power sup
-
plies are correct.
Do
not mount or remove connectors with the power supplied. Doing
so
may result in malfunction.
Locks for Connecting Cables
Ensure that the connectors for connecting cables are securely
locked
before supplying power
.

Precautions
General
Common
Precautions
The
B7AH performs 1-to-1 communications and does not require a
communications master. It cannot be connected to CompoBus/S
transmission
paths from OMRON remote masters.
Do not use the B7AH in locations subject to corrosive gases.
When using the B7AH in locations where a large amount of static
electricity is generated (e.g., molding materials, powder, or fluid
materials
conveyed along pipelines), install the B7AH at least
1 m
away from the source of the static electricity
.
Line Resistance in the T
ransmission Path
If power and signals are transmitted together along 3-core cable,
ensure that the line resistance in the transmission path between
Link
T
erminals is less than 2.5
Ω
. (The same value applies even if
terminal
blocks, connectors, or slip rings are used at points on the
line.)
If the line resistance rises to a value greater than this, the cur
-
rent flowing to 0 V and the line resistance will
cause
a large voltage
drop,
preventing normal
transmission and generating an error
. As a
rough guide, the line resistance with a VCTF cable of thickness
0.75 mm
2
will be 2.5
Ω
per 100 m.
Connection to 10-point B7A Terminals is not possible because
transmission
signals are not compatible.
If
there is a possibility of shocks or vibration, prevent the pins
being
damaged
by securing
the Link T
erminal to the PCB using an (e.g.,
epoxy-based)
adhesive.
Do
not touch the pins. Doing so may cause deformation. In addition,
touching
the pins in an ungrounded state may result in damage to
internal
elements due to static discharge. Use an anti-static mat dur
-
ing
work to ensure that the body is in a grounded state.
Soldering
When
soldering using a soldering iron or a soldering bath, solder in
less than 5 s at a temperature not exceeding 260°C. Do not use
reflow
soldering.
Cleaning
Do
not use highly acidic or highly alkaline
solvents to clean the PCB.
Power
Supply
Be sure to use the specified power supply voltage. Do not use a
power supply that has a large ripple or intermittently generates
abnormal
voltages.
Noise and Miswiring Protection Circuits
If
there is a possibility of noise interference between the power sup
-
ply
pins (+V and –V or VDD and VSS) or at input or output pins (IN00
to
IN15 or OUT00 to OUT15), or if there is a possibility of miswiring
the
signal pin (SIG) and the positive power supply pin (+V or VDD),
include
the protection circuits described on page
68.
Wiring
Do
not wire transmission lines parallel to, and less than 10 cm away
from,
lines carrying
high voltages or currents. If transmission lines
are
installed less than 10 cm away from potential sources of noise,
confirm
that correct operation is possible before using
the Link T
er-
minal
in actual operation.
Do not perform wiring with the power supply turned ON. Doing so
may
cause pins to be
accidentally short-circuited, resulting in dam
-
age
to internal elements and communications failure.
If
the SIG pin and the positive power supply pin or the VDD (+5 V)
pin
are shorted during communications,
the Link T
erminal will mal
-
function
and normal communications will not be possible. Confirm
that power lines are not shorted before turning ON the power
.
Be
sure to apply the specified power supply to the power supply pins
(positive, negative, VDD, and VSS). Applying excessive voltages
(e.g.,
100 V
AC) will cause the Link T
erminal to malfunction and nor
-
mal
communications will not be possible.
Shorting
(no-load state) the OUT pins
of Output Link T
erminals dur
-
ing
communications will cause the Link T
erminal to malfunction. Be
sure
to connect a load within the
specified load current range. When
measuring
the current with a tester
,
measure with the load supplied.

Transmission Errors and Output Signals
Transmission
errors occur in the following cases:
•
When the signal or 0-V wire is disconnected.
•When
the signal is influenced by high-level external
noise or the
signal is excessively deformed because the length of the
transmission
path is more than the permissible distance.
•When
the supply voltage to the Link T
erminals are not within
the
operating
voltage range (12 to 24 V
±10%).
•
Immediately after the Link T
erminals are turned on.
(An error is reset within 300 ms after the power is turned on.)
Output Signals
HOLD:
When an error occurs, the output signals just
before the oc
-
currence
of the error will be maintained.
LOAD
OFF: When an error occurs, all output signals will be turned
OFF.

Precautions
Note: The undermentioned is common for all B7A-series Link Terminals.
General
Each
terminal of the B7A-series should be used for only single sig
-
nal
transmission
without a transmission host. The B7A-series can
-
not
be connected to OMRON’
s SYSMAC BUS Remote I/O System.
Avoid
places subject
to corrosive gasses or continual shock and/or
vibration.
If high-level electrostatic discharge is generated at the
installation
site
(e.g., for transfer of a molding material, powder
, or liquid
through
a pipe), separate the Link Terminals as far as possible from the
source
of the electrostatic discharge.
If
the Input and
Output T
erminals are connected via a three-conduc
-
tor cable to transmit signals with a single power supply (i.e., the
power
supply is connected directly to one of the Link T
erminals and
indirectly
to the other), the transmission distance greatly varies with
the
diameter of the cable. This is due to the potential dif
ference be
-
tween
the current on the 0-V transmission wire and on the 0-V I/O
transmission
line
caused by the resistance of the cable. By increas
-
ing
the diameter of the cable (decreasing its resistance), the trans
-
mission distance can be increased. By reducing the resistance of
the
transmission path to 2.5
Ω
or less for example (i.e., increasing
the
thickness of the wire to 1.25 mm
2
or more), a transmission dis
-
tance
of 160 m will be achieved.
It is recommended that a switch for minute loads be connected to
the
16-point screw terminal model because there is a contact input
current
of only 3 to 6
mA to the model from the connected switch or
relay.
The
Output T
erminal has an error of 300 ms maximum after the Out
-
put
T
erminal is turned on. The user should be well aware of this be
-
fore
using error outputs.
Note: The
10-point and 16-point models cannot be connected to
each
other because their transmission signal data formats
are
not compatible.
Screw Terminal Models
Apply
a torque of 0.78 to 1.18 N
S
m to tighten wiring terminals.
Hold both edges of the terminal cover to open it.
If the Input or Output Terminal is mounted to a panel with screws,
apply
a torque of 0.59 to 0.98 N
S
m to tighten the screws.
Modular Models
Soldering
(with an soldering iron or in a soldering tab) must be com
-
pleted
within 5 s at a temperature of 260
°C or less.
The
supply voltage must be within the operating voltage range. Do
not
use
a power supply which generates irregular voltages or large
ripples.
Do not apply a strong acidic
or alkaline solvent to the printed circuit
board
for removal of the flux. The module of the B7A 10-point model
is
not of closed-mold construction. The solvent must not remain on
the
bottom of the module after the module is cleaned. The module of
the
B7A 16-point model is of closed-mold construction.
The
input and output circuits are not insulated. If
Link T
erminals are
influenced
by external noise, use photocouplers to insulate the I/O
circuits.
Terminals with PLC Connector Models
Apply
a torque of 0.78 to 1.18 N
S
m to tighten wiring terminals.
Be
sure to disconnect the connector unit from the PLC’
s I/O
connec
-
tor
unit when wiring
the screw terminals in order not to impose ex
-
cessive
force on the PLC’
s I/O connector unit.
Use
the B7A in combination
with a PLC correctly
, otherwise the B7A
may
be damaged. The following are correct combinations.
B7A Input Unit and PLC Output Unit
B7A Output Unit and PLC Input Unit
Wiring
Separate
the transmission lines from high
voltage or power lines as
far away as possible and do not wire
the transmission lines in paral
-
lel
with high voltage or power lines. If Link T
erminals are used near a
device
that generates noise, make sure that the Link T
erminals do
not
malfunction due to the noise generated from the device.
Make
sure to turn of
f the Link T
erminals while wiring in order to avoid
a
short-circuiting accident that may damage the internal element(s)
of
the Link T
erminals.
Link
T
erminals will
malfunction if the SIG terminal is short-circuited
with
one of the power terminals or B
jj
terminal. Before turning
the
power on, make sure that the
SIG
terminal is not short-circuited with
these
terminals.
Before
checking the insulation resistance of
the transmission path,
disconnect
the wires from the Link T
erminals.
If
the OUT terminal and positive power terminal of the Output Link
Terminal
is short-circuited during signal transmission, the Link
T
er-
minal
will malfunction. Apply an appropriate load between these ter
-
minals.
When
measuring the current, use a multimeter without disconnect
-
ing
the load.

Precautions
General Precautions
Be careful when touching the
B7AP-S1 Power Coupler during op
-
eration because the surface temperature of the B7AP-S1 Power
Coupler
will rise approximately 20
°
C after the
B7AP-S1 Power Cou
-
pler
starts power transmission. The surface
temperature varies with
the load of the sensing device connected to the B7AP-M1 Power
Coupler
and the transmission distance.
Correct Use
Handling
Use
the B7AP-S1 and B7AP-M1 Power Couplers with the available
B7A
Link T
erminals. Refer to
page
21, B7A Models
.
The M7E-12jj Display Unit, M7E-20jj Display Unit, and B7A
Link
T
erminals with an I/O delay time of 3 ms cannot be used with the
B7AP-S1
or B7AP-M1 Power Coupler
.
Use
the LOAD-OFF model for the B7A
Output Unit to be connected
to
the B7AP-S1. When using a model that allows selection of error
processing, set to the LOAD-OFF mode. This turns OFF signals
right
before an occurrence of a transmission error and prevents un
-
expected signal transmission when the transmission error is
cleared.
Separate
the Power Couplers 8
±
1.5 mm min. away from each other
.
The
distance between the
Power Couplers on standby must be 30
mm
or more.
30
mm min.
Do not supply power to the B7AP-S1 or B7AP-M1 Power Coupler
while connecting the Power Couplers to the B7A Link Terminals.
Connect the Power Couplers to the B7A Link Terminals correctly,
otherwise
the internal circuits of the Power Couplers may be dam
-
aged.
The
SIG terminal must not contact with the power supply terminals,
otherwise
the internal elements may be damaged and normal trans
-
mission
may not be possible.

Mounting
Use nuts and serrated toothed washers and tighten the nuts to
mount
the B7AP-S1 and B7AP-M1 Power Couplers. The tightening
torque
applied to each
of the nuts must be 39 N

Transmission Distance for Stable Signal and
Power Transmission
The
B7AP-S1 Power Coupler has a gauge that is used to adjust the
transmission
distance between the B7AP-S1
and B7AP-M1 Power
Couplers. Use the gauge to adjust the transmission distance to
8 mm,
make sure that the green operation indicator of the B7AP-M1
Power Coupler is lit, and the B7A Output Unit has no error output
before
operating the Power Couplers.

The “approved standards” column in the above table indicates
approval for (UL, CSA, cULus, cUL, NK, or Lloyds) or
compliance
with
(EC Directives) the relevant standard or directive as of the end
of April, 2001. Enquire separately for details on the conditions
required
to meet these standards and directives.
EMC Directive
OMRON
devices that comply with EC Directives also conform to the
related EMC standards so that they can be more easily built into oth

er devices
or the overall machine. The actual products have been
checked
for conformity to EMC standards (see the following note).
Whether
the products conform
to the standards in the system used
by
the customer
, however
, must be confirmed by the customer
.
EMC-related
performance of the
OMRON devices that comply with
EC
Directives will vary depending on the
configuration wiring, and
other conditions of the equipment or control panel on which the
OMRON
devices
are installed. The customer must, therefore, per
-
form
the final check to confirm that devices and the overall machine
conform
to EMC standards.
