options like:
•Relay or transistor output models
•8-point input expansion module
•8-point output expansion module
•20-point I/O expansion module
•Analog input/output
Mixed Analog I/O Module
Quickly incorporate analog signals in your
small-scale control systems with the
CPM1A-MAD01 module. Featuring 2 analog
inputs/1 analog output with constant moni-
toring for ‘broken wire’ and for +/- voltage

Connect any
Operator Interface
Terminal with an
RS-232C adapter.
With this connection,
you can monitor the
process or interface
with the CPM1A directly.
The CPM1A connects
directly to a PC using an
RS-232C adapter. You can
download programs, transfer
data, and
monitor the
status of the
CPM1A from
your PC.

Using the CPM1A-
SRT21 adapter, the
CPM1A can operate
as a slave on a
CompoBus/S
network and use up
to 8 outputs and 8
inputs via control
of a CompoBus/S
master.
System Configuration Options
The CPM1A’s small size lets you pack several connections and usage options into a compact panel. It is
powerful enough to support up to 100 I/O, offer multiple control options, and connectivity to several
different devices including bar code readers, operator interfaces, process and temperature controllers, etc.
1:N Communications
allows multiple
CPM1As to connect
to a PC via a link
adapter and RS-422
adapters. You can
monitor, control and
program up to 32
PLCs from a remote
location.
Use a handheld programmer
to program and download
information directly to the
CPM1A via its peripheral port.
1:1 Link connects a CPM1A to
another CPM1A or any other
Omron PLC, allowing the linked
PLCs to communicate directly
and seamlessly share data.
Expansion I/O increases the CPM1A’s usefulness in solving your
applications. Expand up to three modules (up to 100 I/O points total)
including a mix of relay, transistor (NPN or PNP) or, analog input and
output points all connected via simple ribbon cable connections.

A Complete Family of Micro PLC Solutions
CPM1 is a low cost, and simple
control option with a CE mark
The cost-effective CPM1 micro PLC CPU
is easily set up and has 10, 20, and 30
base I/O and is expandable to 90 I/O.
CE mark is standard on
all versions.
The new, ultra-
slim CPM2C
offers a variety of
communication and
expansion options
The 33 mm wide CPM2C
supports up to 140 I/O (5 expansion modules)
via screw terminal contacts or a connector that
is compatible with several styles of I/O terminals.
Built-in features include a real time clock, RS-232C
port, synchronous pulse control and numerous
expansion options. Communication options include
RS-232C, Omron’s Host Link and no-protocol
communications. The CPM2C also has a combination
RS-232C/peripheral port that can support two devices
simultaneously from one location.
The CPM2A packs
speed, power, control
options, and large I/O capacity
in a micro-sized package
Use the CPM2A’s base I/O of 30, 40, and 60 points to
integrate power, speed, and advanced control into your
small-scale applications. It is expandable to 120 I/O points,
has a built in RS-232C port, removable terminals, and four
high-speed interrupts.
The ultra small SRM1 network
controller supports distributed I/O
Distribute your control with the SRM1
network controller. It offers the flexibility
and power of a small PLC in a distributed
I/O package. It supports multi-point relay
terminal connections or remote
terminal connections up to
500 meters away. Each
module in the distributed I/O
network communicates
directly with the SRM1 via
twisted pair, eliminating
complex cabling and
allowing you to place the
control device close to your
application.
