ELC Programmable Logic Controllers
Introduction
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.
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.
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.

ELC—the scalable solution to
machine control
Power and flexibility in the smallest enclosures
The ELCs pack large controller modularity and power in a world-class
small package. Capable of supporting hundreds of I/O points, these
controllers thrive on putting together just the right mix of I/O into the
smallest cabinets.
All controllers are 24 Vdc powered, and commonly use ELC-PS01 or
ELC-PS02 power supplies to reduce space. There are five different
styles of these controllers: ELC-PB, ELC-PC, ELC-PH, ELC-PA, and
ELC-PV. Each style has different characteristics, but some shared
features: they all have embedded 24 Vdc sink/source inputs and
either 24 Vdc sinking transistor or relay outputs (with one exception
being the ELC-PC controller that supports AC inputs); all controllers
have two communication ports (RS-232 Modbus serial slave port
and an RS-485 Modbus serial master/slave port), and can use
DeviceNet or PROFIBUS-DP communication modules to enable the
controller to be a slave to a remote scanning master; all supply the
power for their attached digital I/O modules through an embedded
I/O bus; all can support distributed I/O (using an ELC-CARS485
adapter module); all have high-speed input/output capability; and all
support a robust instruction set that is programmed using ELCSOFT.
No racks required
A DIN rail lets you add as many as 14 I/O modules—with the
restriction that no more than eight modules may be analog or
specialty I/O per system. There are 17 different digital, analog,
and specialty modules. Just snap on, and slide into place.
All connections are done automatically.
Built-in potentiometers
The ELC-PC, ELC-PH, and ELC-PV controllers have two built-in
potentiometers that can be scaled and used for many applications
such as increasing and decreasing the speed of a drive/motor.
Built-in display
An integral LED display on the ELC-PA provides user-assigned
process monitoring, error messages, alarms, display counts,
and more.
ELC programming software
Program on your PC and download to the ELC through a serial cable
or over Ethernet. Make online changes, and monitor and remote-
control the run/stop operation. Software wizards simplify the
programming process and, with ELCSOFT 2.02 or later, offline
simulation is supported so you can program, troubleshoot, and verify
your ELC system without the need for physical inputs and outputs
attached to your controller.

ELC’s value-added differences
Five controller styles:
PB base model—14 I/O (8 in/6 out) More than 130 instructions
provide all the power you need; two serial ports for
master/slave communications
PC clock/calendar model—12 I/O (8 in/4 out) 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 (6 in/4 out) Same as the PC model,
and includes embedded analog I/O
PH high-speed model—12 I/O (8 in/4 out) Same as the PC model,
plus the ability to capture or output 100 kHz pulses
PV high-speed model—28 I/O (16 in/12 out) Almost 10 times
faster than the other ELCs, 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

ELCM—compact, modular, and ready
to communicate
The ELCM controllers merge the best parts of a “brick” controller
with the flexibility and power of a modular system. Like the ELCB,
the ELCM is an “all-in-one” form factor controller—embedding
24 Vdc sink/source inputs and either 24 Vdc sinking transistor or
relay outputs, logic processing, and an embedded 100–240 Vac at
50/60 Hz (nominal) power supply into a compact form factor. But the
ELCM controllers may also be expanded with digital, analog, and
specialty I/O modules.
If your application is likely to expand over time or requires a variety
of input or output types, the ELCM is the controller for today
and tomorrow. The ELCM controllers come in 10 varieties with
embedded 24 Vdc digital sink/source inputs and either 24 Vdc
sinking or relay outputs. Two of these controllers (ELCM-PA20AADR
and ELCM-PA20AADT) also have four analog inputs and two analog
outputs. To expand the ELCM controller, simply attach modules
to the right side. The ELCM supports a maximum of 14 extension
modules, where up to 8 of them can be analog or speciality
modules. There are 13 different digital, analog, and specialty
expansion modules. Communication is also a strength with these
three comm port controllers—port 0: RS-232 Modbus serial master/
slave; ports 1 and 2: RS-485 Modbus serial master/slave ports. The
ELCM controllers also program using ELCSoft (version 2 and higher).
The ELCM controllers offer flexibility and processing power not
usually found in small brick controllers.
No racks required
A DIN rail lets you add up to 14 expansion I/O modules, giving you
the ability to add I/O as your appropriations needs grow, or to mix
I/O types for more complex systems.

ELCB—when just enough I/O is just
what you need
The ELCB controllers are designed to be “just enough” controllers.
These non-expandable controllers are designed for applications
where cost is more critical than I/O flexibility.
Budget balanced with value
When the application calls for simplicity and the budget calls for
value, the ELCB family is an excellent choice.
There are 10 different sized controllers equipped with 24 Vdc sink/
source inputs and either 24 Vdc sinking transistor or relay outputs.
Communication ready
Communication between controllers, to local operator interface
devices, or to supervisory/programming devices is accomplished
through an RS-232 Modbus serial slave port or through an RS-485
Modbus serial master/slave port.
Low-profile designs
These compact controllers contain 100–240 Vac @ 50/60 Hz
(nominal) power supplies to eliminate the need for an external DC
supply. They also have an embedded 24 Vdc output power supply
for sensors. Smaller controllers (with 10 or 14 I/O points) supply
up to 200 mA; larger controllers (20 to 40 I/O points) provide up
to 300 mA for input sensors.
Simplified configuration
Program your ELCB with ELCSoft (version 2 and higher), an
easy-to-use programming environment with high-end capabilities,
including offline simulation.
