Performance Parameters:

  • Input Points: 16
  • Input Voltage: 24 VDC
  • Input Current: 7 mA
  • Response Time: 8 ms max.

Material Composition:

  • Industrial-grade electronic components
  • Multi-layer printed circuit board
  • Plastic housing
  • Removable terminal block

Structural Features: The unit features a 35mm width design with a removable terminal block on the front. This allows for quick replacement of the unit without disconnecting field wiring.

Working Principle: The unit receives DC 24V signals from field devices. These signals pass through photocouplers for isolation and are then processed by the internal logic circuit. The status of each input is updated in the PLC’s I/O memory area.

Installation Requirements:

  • Mount on CJ series CPU rack or expansion rack
  • Connect field wiring to the removable terminal block
  • Ensure correct polarity for DC inputs
  • Use appropriate wire gauges and crimp terminals

Usage Notes:

  • Verify the input voltage is within the rated range (20.4 to 26.4 VDC).
  • Do not connect AC voltage to this unit.
  • Ensure the total current consumption is within the power supply capacity.
