Omron PLC CPM1A Series

CPM1A

Compact PLC series

CPM1A


Setting a standard for micro PLCs, the CPM1A packs all basic functions into a compact size. Four CPU sizes are available, each with a choice of AC or DC power, relay or transistor outputs. Select any combination of power supply, output, and the number of I/O points to meet your needs.


Space-saving Integration for Compact machines and Small-scale Control cabinets

Ultracompact Size

Ten-I/O-point AC models measure only 90 mm x 66 mm x 70 mm (H x W x D), and contain all basic PLC functions.

A Wide Variety of Models Handling from 10 to 100 I/O Points

By combining CPU Units having from 10 to 40 I/O points with 20-I/O-point Expansion I/O Units, CPM1A PLCs can be configured for 10 to 100 I/O points.

Programming by Programmable Terminal

Use of the optional Communications Adapter (RS-232C or RS-422 conversion) enables fast Host Link or NT Link communications with an OMRON Programmable Terminal. This makes it possible to program the CPM1A on the PT screen, greatly simplifying maintenance tasks.

High-speed Processing

Processing is fast, e.g., 0.7-μs AND LD / OR LD and 16.3-μs MOV instructions, allowing high-speed execution of even lengthy programs. Integrated interrupt and pulse catch inputs also handle high-speed pulses that occur within one program cycle.

Versatile Functions in a Compact Body

A large program capacity and instruction list handle even complicated control tasks with ease. 
• User memory: 2,048 words 
• Data memory: 1,024 words 
• Timer/counter: 128 points 
• Basic instructions: 14 types 
• Application instructions: 79 types 
• Analog setting dials: 2 points (built-in)

Pulse Output

CPM1A CPU models with transistor outputs can output pulses with a maximum frequency of 2 kHz. Combining these models with a Stepping Motor Driver or Servo Driver enables easy positioning operation.
