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 AC 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 CS1 series CPU rack or expansion rack.
- Connect field wiring to the removable terminal block.
- Ensure proper grounding.
Usage Notes:
- Verify the input voltage is within the rated range (85 to 132 VAC).
- Do not connect DC voltage to this unit.
- Ensure the total current consumption is within the power supply capacity.
