Product Overview
Controllers
There are five controller styles:
ELCB Brick-Style Controllers
The ELCB controllers are the
simplest and most affordable
members of the ELC
portfolio. With ELCB, the
focus is on “just enough
control” for applications up
to 40 I/O points. These
controllers pack a lot into a
small, low-profile package.
Like the ELCM controllers,
these controllers are AC
powered and provide 24 Vdc
sensor power. But unlike the
rest of the ELC family, the
ELCB controllers do not offer
expansion I/O. The ELCB is
great as a standalone
controller, or is capable of
networking with other
controllers, operator
interfaces, drives, or other
Modbus
®
serial devices.
ELCM Modular Brick-Style
Controllers
The next member of the ELC
portfolio of controllers is the
ELCM. This midrange family
comprises “brick-style”
controllers, with expansion
I/O modules. These all-in-one
controllers combine inputs,
outputs, logic processing, and
an integrated AC power
supply into a compact
package—but also provide
the means to expand as
applications change or grow.
The controller also provides
24 Vdc power for sensors,
eliminating the space, wiring,
and expense of an additional
power supply. And with three
communication ports, the
ELCM is able to interface into
a local operator interface,
connect to other controllers
or supervisory computers,
and still maintain an open port
for programming.
ELC Modular Controllers
The ELC lineup is focused
on compact size, powerful
features, and affordability.
Whether your needs involve
discrete standalone control,
necessitate distributed
control networks, or even
a control system, using
centralized control with
distributed I/O, ELCs provide
the solution your application
demands.
While the ELCs are perfectly
suited for small applications
of <40 I/O with a diverse mix
of I/O, they can also expand
to hundreds of I/O points
when needed. These
controllers are modular,
with a wide range of digital,
analog, thermocouple, RTD,
and even motion expansion
modules. Despite a world-
class small footprint—with
controllers as small as 1.00-
inch wide, these controllers
perform like much larger
PLCs. With online editing,
high-speed processing (basic
instructions
as fast as 0.24
microseconds),
multiple high-
speed inputs/outputs (up to
200 kHz), and multiple
independent master
communication channels,
these controllers excel where
only the largest PLCs could
go only a few years ago.
