Structural Features: The CPU unit features a compact form factor with a built-in RS-232C port and a slot for Memory Cards. It connects to I/O modules via the CJ1 series bus connector system (no backplane required).

Working Principle: The CJ1M-CPU11 executes user programs stored in its memory, reads input signals from connected I/O units, performs logic and arithmetic operations, and updates output signals. It manages data exchange between the CPU, I/O modules, and communication networks.

Installation Requirements:

  • Mount on DIN rail or panel
  • Connect I/O modules to the right of the CPU
  • Connect power supply unit (CJ1W-PA/PD) to the left of the CPU
  • Ensure proper grounding

Usage Notes:

  • Use CX-Programmer version 3.3 or higher for programming.
  • Ensure the total current consumption of the system is within the power supply unit’s capacity.
  • Do not install the CPU in environments with excessive vibration or corrosive gases.
