Eaton Logic Controller (ELC)
The Eaton Logic Controller (ELC) puts sophisticated
PLC logic, an extensive set of I/O, and communications
capabilities in packages as small as 1"W x 2.4"D x 3.5"H.
Compact, modular, and ready to
communicate. It’s the cost-effective
solution to machine control.

The right amount of I/O.
Why pay for functionality you don’t need? Why be trapped
with functionality you can’t scale to meet changing needs?
Eaton is changing everything with the ELC.
At less than half the size of most PLCs, the Cutler-Hammer
ELC is an ideal solution when space is at a premium and
specialized I/O needs present themselves.
Space saving. Cost saving.
This space-saving design is as perfectly at home in a
small machine control station as it is in an MCC and other
enclosed applications where space is critical. Reduced space
also means smaller control cabinets and panels, or more
capability in the same amount of space. However you look
at it, the ELC means value.
Half the size of most PLCs, the
Cutler-Hammer ELC puts the
right amount of I/O right where
you need it. ELC Controller and Expansion Modules
ELC Programming Software
Program on your PC and download to the ELC through a serial cable or over
Ethernet. Make online changes, monitor and remote control the run/stop
operation. Software wizards simplify the programming process.

Machine space
is measured in inches.
The ELC is measured
the same way.
Add value with the ELC.
While the ELC is perfectly suited for small applications of
40 I/O and less, it can also be expanded to 512 I/O. What’s
more, with the ELC’s two communication ports it can
provide a network of distributed controls. The ELC is
capable of sharing information with other control and
operator interface devices. Its small size allows for reduced
panel size, and saves valuable machine space.

ELC’s value added
differences.
5 controller styles:
PB Base Model— •
14 I/O (8i/6o)
Over 130 instructions
provide all the power
you need. Two serial
ports for master/slave
communications.
PC Clock/Calendar Model—
•
12 I/O (8i/4o)
Same as the PB model,
plus clock/calendar,
twice the program steps,
distributed I/O, and
retentive data storage.
PA Analog Model—
•
10 I/O (6i/4o)
Same as the PC model,
plus embedded analog I/O.
PH High-Speed Model—
•
12 I/O (8i/4o)
Same as the PC model,
plus the ability to capture
or output 100 kHz pulses.
PV Advanced Model—
•
28 I/O (16i/12o)
Almost 10 times faster than
the other ELC controllers,
high speed I/O to 200 kHz,
and additional advanced
features. Add left side
expansion modules for
master communications
on networks such as
Ethernet and DeviceNet™.
More Controller Features

•
and high-speed pulse

counts per module.
2 Modbus
•

1 master/slave.
Over 200 instructions to
•
choose from: Floating point
math, communications,
16- and 32-bit math,
logical, block move, block
compare, retentive data
storage, conversion, time
base from clock/calendar.
ELC benefits solve
applications:
Size—large PLC features in
a 1" package. Half the size of
competitive offerings. ELC
can retrofit more I/O in the
same space or allow more
cost savings by reducing
cabinet size.
Flexibility—ELC controllers
expand from 28 to 512 I/O
on the PV models, and 10 to
256 I/O on all other models.
Add only the amount of
•
I/O you need. Choose I/O
counts as small as 2 points
and as large as 16 points
per module.
DIN-rail mounting lets you
•
add as many modules as
needed by snapping them
into mating connectors.
Large PLC Features—
Multiple communications
ports, distributed I/O
capability, high speed
counters, high speed pulse
outputs, interrupts, timer
resolution to 1ms, PIDs,
plus much more.
Software—ELCSoft
programs in standard ladder
or sequential function chart
programming.
Display registers “in use”
•
and modules attached to
the ELC.
Monitor runtime
•
applications. Force (except
PB model), and enter/
modify register values.
Wizards aid programming of
•
ELC Link for distributed I/O,
standard communications,
high speed counters,
pulse outputs, positioning,
interrupts, PIDs, and
extension module setup.
Communications—
Connecting to networks is
easy on Modbus®, Modbus
TCP, DeviceNet™, and
Profibus.
No racks required
A DIN- rail lets you add as many modules as desired. Just snap on, and slide
into place. All connections are done automatically.
Built-in display
An integral LED display on some models provides user-assigned process
monitoring, error messages, alarms, display counts and more.
