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 3.5"H x 2.4"D.

Compact, modular, and ready to

communicate. It’s the cost-effective

solution to machine control.

The Eaton Logic Controller.

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 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

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.

EATON CORPORATION Programmable Logic Controller

Machine space

is measured in inches.

The ELC is measured

the same way.

While the ELC is perfectly suited for small applications of

40 I/O and less, it can also be expanded to hundreds of

I/O points. 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

• High-speed pulse capture and

high-speed pulse output on all

controllers.

• Broad selection of AC/DC in,

relay/transistor and high current

output modules.

• Large selection of analog In/

Out in various I/O counts per

module.

• 2 Modbus

(ASCII / RTU) serial

ports: 1 slave only,

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 10 to hundreds of

I/O points. Expand with up to

16 modules (no more than 8

analog/specialty modules).

• 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

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.
