Digital Indicators K3HB Series (Pulse Input Series) 1
Digital Indicators
K3HB Series (Pulse Input Series)
The K3HB Series has been made complete with
the addition of Digital Signal Input Models.
Features
Red-Green Display Allows Easy
Recognition of Judgment Results
The measurement value display can be set to switch between red
and green in accordance with the status of comparative outputs. This
means that the status can be easily seen at a distance.
Position Meter Enables Easy Monitoring of
Operating Status Trends
The present value with respect to the measurement or display range
(full scale) can be viewed on a bar display. The operating status can
be grasped intuitively, allowing easy judgment of levels and threshold
values.
Short Body with Depth of Only 95 mm
(from Behind the Front Panel)
A short body of only 95 mm (see note) contributes to the
development of slimmer and smaller control panels and installations.
Note: Depth of DeviceNet models is 97 mm.
50 kHz High-speed Pulse Measurement
(K3HB-R)
Supports high-speed pulse measurement (up to 50 kHz) of rotary
encoders or any ON/OFF pulse signal, which enables rotational
measurement of objects rotating at high speeds.
Note: No-voltage contacts of up to 30 Hz are supported.
Measurement of Wide Range of Pulse
Interval Times (K3HB-P)
Measures and displays the results of the pulse interval between two
points. The pulse interval measurement range is broad, from 10 ms
to 3,200 s.
High-speed Up/Down Counting Pulse
Measurement (K3HB-C)
Perfect for high-speed measurement of rotary encoders or any
ON/OFF pulse signals. Cumulative pulse input is 50 kHz, quadrature
pulse inputs are 25 kHz, and up/down pulse inputs are 30 kHz.
Note: No-voltage contacts of up to 30 Hz are supported.

2Digital Indicators K3HB Series (Pulse Input Series)
Features
Many I/O Variations for Discrimination, Control, and Information Applications
Digital Indicators are used in a wide variety of applications, from an electronic measurement value display or equipment/device operating status
display to a host communications interface in monitoring and control systems. OMRON provides a complete lineup for a variety of input and control
output applications to meet all your application requirements.
Select a Comparative Output Pattern to
Suit the Discrimination or Control
Application
•The output pattern for comparative outputs can be selected. In
addition to high/low comparison with set values, output based on
level changes is also possible. (Use the type of output pattern
appropriate for the application.)
Note: The HH, H, L or LL outputs must be set in that order for the zone
outputs to output correctly.
(This is because the comparative set values and outputs for
standard and level outputs are in a 1-to-1 relationship, whereas
the meaning of zone outputs depends on the settings of all the
comparative set values.)
Lineup Includes DeviceNet Models
Enabling High-speed Data
Communications with PLCs without
Special Programming
•DeviceNet compliance enables high-speed data transmission by
allocating setting and monitoring parameters in the I/O memory of
the PLC. This capability greatly reduces labor spent in developing
communications programs.

F2 to F5: Displays the calculation result for two rotation (rpm) speeds.
F6: Displays the passing time calculated from the circumferential speed and the length
of the processing stage for one input.
The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is
to count the ON/OFF time (T) for input sensor or other device inputs using the internal system
clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and
displayed as the rotation (rpm) speed.
Input sensor or other input pulse ON/OFF time (T) = Frequency (f) =
•Rotation speed (rpm) = f × 60
•Circumferential speed = Roll circumference × Rotation speed (rpm)
•Passing time=
These calculations are automatically made internally and displayed whenever any input pulse
is received.

Rotary Pulse Indicator K3HB-R 9
■What Is Prescaling?
To make calculations using the input pulse to display rotation (rpm)
or circumferential speed, the number of pulses per rotation or the
length of the circumference must be multiplied by a certain
coefficient. This coefficient is called the prescale value.
Rotation speed (rpm) = f × 60 × a
f: Input pulse frequency (No. of pulses per second)
a: Prescale value
If there are 5 pulses per rotation, then
a = 1/5 (= 0.2 = 2 × 10-1)
and an accurate rotation speed (rpm) can be calculated.
The actual setting is X = 2.0000 (mantissa) and Y = 10-1 (exponent).
■What Is the Auto-zero Function?
(Set this function before using the Digital Indicator.)
If a function f1 to f6 is set, the frequency can be force-set to zero if
there is no input pulse for a set period. This period is called the auto-
zero time. Set the auto-zero time to slightly longer than the longest
input pulse interval. (The display will not easily return to zero if the
auto-zero time is too long or left at the default setting.)
Time Unit Settings
Note: Time unit can be set only when passing time (F6) is selected.
Input Type Setting
Note: Set to 10 or 11 when there is a large variation in the display.
The largest measurement range is 30 Hz.

Operation
■Functions (Operating Modes)
F1 to F6
These functions use the internal system clock to measure the time between pulses or the pulse ON time and then display time measurements or
a variety of other calculations.
Function name Function No.
Passing speed f1
Cycle f2
Time difference f3
Time band f4
Measuring length f5
Interval f6
The time (T) between input A pulse and input B pulse
is measured by the internal system clock. If, for
example, the system clock measures 100,000 counts
during time T, then
T = 1 system clock count (0.5 µs) × 100,000
T = 0.05 s
F1 (the passing speed) is calculated internally
using the formula × 60 (m/min), and the
display, in this example, would be × 60=
1200 (m/min).

■What Is Prescaling?
To make calculations using the input pulse to display the passing speed between two points, the distance between the two points and the display
unit must be set and the internally measured time multiplied by a certain coefficient. This coefficient is called the prescale value. (For information
on settings details, refer to the User's Manual.)

■What Is Prescaling?
Prescaling converts the count value to any numeric value.
To disp l ay @@@@.@ mm in a system that outputs 250 pulses for a 0.5-m feed,
the length per pulse = 500 mm (0.5 m) ÷ 250 = 2.
1. The prescale value for the K3HB-C is set using the mantissa X × exponent Y,
so the prescale value = 2.0000 × 10°,
X = 2.000, and Y = 00.
2. Next, set the decimal point position for one digit to the right of the decimal point:

■BCD Output Timing Chart
A REQUEST signal from a Programmable Controller or other external device is required to read BCD data.
Single Sampling Data Output
The data is set in approximately 30 ms from the rising edge of the
REQUEST signal and the DATA VALID signal is output.
When reading the data from a Programmable Controller, start
reading the data when the DATA VALID signal turns ON.
The DATA VALID signal will turn OFF 40 ms later, and the data will
turn OFF 16 ms after that.
Continuous Data Output
Measurement data is output every 64 ms while the REQUEST signal
remains ON.
Note: If HOLD is executed when switching between data 1 and data
2, either data 1 or data 2 is output depending on the timing of
the hold signal. The data will not go LOW.

Outputs
Standard, zone, and level comparative output patterns can be
selected for comparative outputs.
Prevents comparative outputs from chattering when the
measurement value fluctuates slightly near the set value.
Holds the output status when a comparative result output other than
PASS turns ON.
Comparative results other than PASS and error signals can be
output from the PASS output terminal.
Delays turning OFF comparatives for a set period. This can be used
to provide sufficient time to read the comparative output ON status
when the comparative result changes at short intervals.
Turns ON the comparative output for a specific time.
Reverses the output logic of comparative results.
Measurements can be stopped for a set time using an external input.
Output operation can be checked without using actual input signals
by using the keys to set a test measurement value.
A current or voltage proportional to the change in the measurement
value can be output.
The comparison outputs can be kept OFF until the measurement
value enters the PASS range.
Display
The display value can be set to the present value, the maximum
value, or the minimum value.
The present value display color can be set to green or red. The color
of the present value can also be switched according to the
comparative output.
When the input changes rapidly, the display refresh period can be
lengthened to control flickering and make the display easier to read.
The present measurement value can be displayed as a position in
relation to the scaling width on a 20-gradation position meter.
The input signal can be converted and displayed as any value.
Select whether or not to display the comparative value during
operation.
Automatically returns the display to RUN level when there are no key
operations (e.g., max./min. switching, bank settings using keys).
Other
Holds the maximum and minimum measurement values.
Switch between 8 comparative value banks using the keys on the
front panel or external inputs. A set of set comparative values can be
selected as a group.
Any bank settings can be copied to all banks.
The measured value can be recorded when the power supply is
interrupted.
The K3HB can be calibrated by the user.

Common Precautions
■Precautions
!WARNING
!CAUTION
Precautions for Safe Use
1. Do not use the product in the following locations.
•Locations subject to direct radiant heat from heating equipment
•Locations where the product may come into contact with water
or oil
•Locations subject to direct sunlight
•Locations where dust or corrosive gases (in particular, sulfuric
or ammonia gas) are present
•Locations subject to extreme temperature changes
•Locations where icing or condensation may occur
•Locations subject to excessive shocks or vibration
2. Do not use the product in locations subject to temperatures or
humidity levels outside the specified ranges or in locations prone
to condensation. If the product is installed in a panel, ensure that
the temperature around the product (not the temperature around
the panel) does not go outside the specified range.
3. Provide sufficient space around the product for heat dissipation.
4. Use and store the product within the specified temperature and
humidity ranges. If several products are mounted side-by-side or
arranged in a vertical line, the heat dissipation will cause the
internal temperature of the products to rise, shortening the
service life. If necessary, cool the products using a fan or other
cooling method.
5. The service life of the output relays depends on the switching
capacity and switching conditions. Consider the actual application
conditions and use the product within the rated load and electrical
service life. Using the product beyond its service life may result in
contact welding or burning.
6. Install the product horizontally.
7. Mount to a panel between 1 and 8-mm thick.

interlock circuits, or limit circuits, to ensure safety in the
system if an abnormality occurs due to malfunction of the
product or another external factor affecting the product's
operation.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or filings from installation to enter the
product. Doing so may occasionally result in minor
electric shock, fire, or malfunction.
Do not use the product in locations where flammable or
explosive gases are present. Doing so may occasionally
result in minor or moderate explosion, causing minor or
moderate injury, or property damage.
Do not attempt to disassemble, repair, or modify the
product. Doing so may occasionally result in minor or
moderate injury due to electric shock.
Do not use the equipment for measurements within
Measurement Categories II, III or IV (according to
IEC61010-1). Doing so may occasionally cause
unexpected operation, resulting in minor or moderate
injury, or damage to the equipment. Use the equipment
for measurements only within the Measurement Category
for which the product is designed.
Perform correct setting of the product according to the
application. Failure to do so may occasionally cause
unexpected operation, resulting in minor or moderate
injury, or damage to the equipment.
Ensure safety in the event of product failure by taking
safety measures, such as installing a separate monitoring
system. Product failure may occasionally prevent
operation of comparative outputs, resulting in damage to
the connected facilities and equipment.
Tighten the screws on the terminal block and the
connector locking screws securely using a tightening
torque within the following ranges. Loose screws may
occasionally cause fire, resulting in minor or moderate
injury, or damage to the equipment.
Terminal block screws: 0.43 to 0.58 N·m
Connector locking screws: 0.18 to 0.22 N·m
Make sure that the product will not be adversely affected
if the DeviceNet cycle time is lengthened as a result of
changing the program with online editing. Extending the
cycle time may cause unexpected operation, occasionally
resulting in minor or moderate injury, or damage to the
equipment.
Before transferring programs to other nodes or changing
I/O memory of other nodes, check the nodes to confirm
safety. Changing the program or I/O memory of other
nodes may occasionally cause unexpected operation,
resulting in minor or moderate injury, or damage to the
equipment.

20.Do not pull the DeviceNet communications cables with excessive
force or bend them past their natural bending radius.
21.Do not connect or remove connectors while the DeviceNet power
is being supplied. Doing so will cause product failure or
malfunction.
22.Use cables with heat resistance of 70°C min.
■Noise Countermeasures
1. Do not install the product near devices generating strong high-
frequency waves or surges, such as high-frequency welding and
sewing machines.
2. Mount a surge suppressor or noise filter to peripheral devices
generating noise, in particular, motors, transformers, solenoids,
and magnet coils.
3. In order to prevent inductive noise, wire the lines connected to the
terminal block separately from power lines carrying high voltages
or currents. Do not wire in parallel with or in the same cable as
power lines. Other measures for reducing noise include running
lines along separate ducts and using shield lines.
