CPM2C Micro Controller

Fast, Capable and Compact
Omron is powerful CPM2C micro controller redefines the traditional micro PLC. The CPM2C is 33 mm width allows it to fit into small spaces, offers 119 instructions, and has processing speeds rivaling many small PLCs. The 20 I/O units with relay outputs are the smallest in the industry. Multiple communication options along with advanced motion control features enable the CPM2C to provide a powerful solution to virtually any small-scale control application.
  • Ultra compact design with 33 mm width
  • Built-in combination RS-232C/Peripheral port
  • Transistor Outputs expandable to 192 I/O (CPU + 5 Modules), Relay Outputs expandable to 180 I/O (CPU + 5 Modules)
  • Screw terminal, Fujitsu and MIL (flat ribbon) style connections
  • Connect high density MIL and Fujitsu models to Omron realy or terminal blocks for easy wiring and choice of I/O style
  • 4K Program memory
  • Synchronized pulse control allows synchronization of input devices to control devices
  • Up to 5 expansion I/O modules for up to 192 total I/O points
  • Optional Real-Time Clock
  • Multiple High-speed counter inputs
  • 10 kHz pulse outputs

Communication and Expansion

Serial Communication

Direct Connection to PC  Built in serial port allows direct connection to CPU
  • Combination cable provides 2 simultaneous ports (Peripheral / RS-232C) from one location
  • Connect directly to serial devices such as a printer, modem, or a bar code reader.
  • Download programs from a PC directly to CPM2C serial port
1:1 connection to other Omron PLCs allows CPUs to seamlessly share data
  • CPM2C-CIF01 adapter allows use of dual RS-232C ports

Peripherial Communication

Operator Interface and Programming console
  • Combination cable provides 2 simultaneous ports (Peripheral / RS-232C) from one location
  • Connect directly to Omron programming devices
  • Connect directly from the CPU's peripheral port to an Omron op­erator interface terminal with an XM2Z cable (NT21/31/631/20/ 600/11, NS Series)
  • Connect direct from the CPM2C CPU peripheral port to the NT2S using the NT2S-CN223-V1 and NT2S-CN224-V1
  • Connect to additional RS-232C adapter or RS-422 adapter

Expansion

CPM2C System

Easy snap-on expansion
  • Connect up to 5 expansion modules for up to 192 total I/O points
  • Modular expansion allows addition of input, output or combination I/O modules.
  • 8, 10, 16, 20, 24 or 32 point modules available
