ELC Product Family Overview

ELC Modules

The Eaton Logic Controller (ELC) is our
latest offering into the PLC (Program­mable Logic Controller) marketplace.
With the latest technology, this
reduced sized ELC with its abundant
module selection will provide a “Just
Right” concept of providing only what
you want for the price you need.

■

Size – Providing large PLC features/

functions in a small 1" package. ELC is
1/3 the size of a D50, offering identical
and even a larger feature set than the
D50. ELC can provide 46 I/O in the
space that a D50 could provide 14 I/O.

■

Flexibility – ELC controllers can

handle I/O counts from 10 I/O to 256
I/O using the same controller. ELC
eliminates the process of counting
I/O and deciding which controller to
use, ELC is the only one needed.
ELC modules come in many flavors
of I/O from modules containing
4 in / 4 out to modules containing
8 in / 8 out. ELC is not a rack based
system — it simply mounts to a DIN
rail. Add modules by simply snap­ping them into the mating connec­tors and closing the attached locks.

■

Large PLC Features – ELC has the

feature set of larger PLCs, from its
multiple communications ports,
remote I/O ability, data storage, high
speed counter, high speed pulse
outputs, interrupts, timer resolution
to 1 ms, PID, plus much more.

Product Description

ELC Controllers

The ELC family offers four styles of
controllers. These controllers offer
combinations of the following features:

Software – ELCSoft, the software,

configures the entire line of ELC
controllers. Priced less than $200,
it programs in standard ladder logic
and sequential function chart pro­gramming. It will aid in knowing
what registers are in use and what
modules are attached to the ELC. It
monitors the runtime application,
allows forcing (except basic), and
entering values. Software wizards
aid programming of remote I/O,
standard communications and PIDs.

Power of One – ELC communicates

easily to MVX drives, eliminating
the need to operate drives by analog
voltage/current or digital I/O. ELC
can access all of the parameters in
the MVX by serial communications,
saving OEM money. ELC communi­cates to
TCP gateway. This allows ELC to
control the
desired. This will also allow
be used in communicating MCC
applications where the ELC can be
either a DeviceNet™, Profibus, or
ModbusTCP communicating MCC.
ELC communicates to PowerNet
Modbus products, allowing ELC
connectivity to Switchgear and
PowerNet applications.

Price – Following the “Just Right”

concept, ELC is priced correctly to
please customers.

ELC Modules

ELC Expansion Modules

ELC expansion modules provide the
correct amount of I/O for application
solutions. Choose 4, 8, or 16 I/O. Any
number of expansion modules can be
added to the ELC processor to create
256 I/O (128 Inputs and 128 Outputs
maximum).

ELC Specialty Modules

In addition the to expansion I/O, spe­cialty modules like Analog In, Analog
Out, Platinum Temperature, Thermo­couple, DeviceNet, PROFIBUS DP and
Switch Module, etc. can be added. Use
the ELC-485APTR to easily connect to
the RS-485 port of MVX drive, ELC con­trollers and other devices.
