ELC Programmable Logic Controllers
ELC Controllers / Modules
ELC Product Family Overview
ELC Controller and Expansion Modules
The Eaton Logic Controller (ELC) is
Eaton’s latest offering into the PLC
(Programmable Logic Controller)
marketplace. This small sized device,
with its abundant module selection,
provides all of the big PLC features
you need at a micro PLC price.
■
Size – Large PLC features with con-
trollers as small as 1-inch in width.
Half the size of competitive offer-
ings. ELC can fit more I/O in the
same space and allow cost savings
by reducing cabinet size.
■
Flexibility – ELC controllers expand
to over 500 points of I/O on the PV
models and over 230 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, inter-
rupts, 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, position-
ing, interrupts, PIDs and exten-
sion module setup.
■
Communications – Connecting to
networks is easy on Modbus
 ,
Modbus TCP, DeviceNet™, and
PROFIBUS.
Using these technologies, the ELC
can connect to communicating
MCCs where the ELC is a master on
DeviceNet or Modbus TCP. ELC also
communicates to PowerNet products
over Modbus and Modbus TCP, provid-
ing connectivity to switchgear and
PowerNet applications.
Of course, the ELC communicates
seamlessly to Eaton’s operator
interface products.
ELC Controllers/Modules
Product Description
ELC Controllers
The ELC family offers five styles of
controllers. These controllers offer
combinations of the following features:
■
High-speed pulse capture and
high-speed pulse output, up to
200 kHz.
■ Up to 22 interrupts.
■
Large selection of discrete I/O
modules including AC/DC in,
relay/transistor out, and high
current relay out.
■
Large selection of specialty modules
including analog in, out, combined,
thermocouple, RTD Platinum.
■
Over 200 instructions to choose
from: Floating point math, commu-
nications, 16- and 32-bit math,
logical, block move, block compare,
retentive data storage, conversion,
time base from clock/calendar.
■
2 Modbus (ASCII or RTU) serial
ports: 1 slave only, 1 master/slave.
■
Network communications on
Modbus TCP, DeviceNet and
PROFIBUS.
■ ELC controller can be wired for
remote I/O communications
(except the PB model).
ELC Modules
ELC Expansion Modules
ELC expansion modules provide the
correct amount of I/O for application
solutions. Choose from a wide selec-
tion of 4, 6, 8 and 16 point I/O modules
to create a system with up to 508
points of I/O (256 inputs and 252
outputs maximum).
ELC Specialty Modules
In addition to discrete expansion I/O,
specialty modules like Analog In,
Analog Out, Platinum Temperature,
Thermocouple and Switch Modules
are available.
The RS-485 adapter can easily connect
an MVX9000 drive to a network of
ELCs on Modbus. DeviceNet and
PROFIBUS DP slave modules are
available for right side mounting to
all controllers, while Ethernet and
DeviceNet scanner specialty modules
can be added to the left side of the
ELC-PV controllers.
