  • Capable of switching both AC and DC loads
  • Removable terminal block for easy wiring
  • LED indicators for output status
  • Galvanic isolation between outputs and internal circuit

Application Scenarios:

  • Controlling solenoids and valves
  • Indicator lamp control
  • Contactor control for motors
  • General purpose switching
  • Alarm output

Performance Parameters:

  • Output Points: 16
  • Output Type: Relay
  • Max Switching Capacity: 2 A at 250 VAC / 24 VDC
  • Response Time: 15 ms max.

Material Composition:

  • Electromechanical relays
  • Multi-layer printed circuit board
  • Plastic housing
  • Removable terminal block

Structural Features: The unit features a compact 31mm width with a removable terminal block. The front panel displays LED indicators for each output point.

Working Principle: The PLC CPU sends digital signals to the unit, which energizes the internal relays. When a relay is energized, its contacts close, completing the circuit for the external load.

Installation Requirements:

  • Mount on CJ series CPU rack or expansion rack
  • Connect load wiring to the removable terminal block
  • Ensure proper ventilation for heat dissipation
  • Use surge absorbers for inductive loads

Usage Notes:

  • Do not exceed the maximum switching capacity (2 A).
  • Relay outputs have a limited mechanical life; consider transistor outputs for high-speed switching.
  • Ensure the load voltage matches the relay rating.
