Wiring

Power supply: DC24V connected to terminal CN1.

Input / Output: Peripheral signals connected to CN2/CN3, single-ended grounding of the shield wire.

Grounding: Reliable connection of the board card ground to the control cabinet ground.

IV. Maintenance and Care

Daily: Observe the RUN/ERR lights to confirm the normal status of I/O.

Regularly (every 3 months): Power off cleaning; Check for no looseness or oxidation of connectors; Tighten the terminals.

Long-term: Avoid high temperature, humidity, and strong vibration; Store spare parts dry and sealed.

V. Fault Troubleshooting

I/O no response

Check DC24V power supply; Reinsert the board card; Check for external line short circuit / open circuit.

Input abnormality

Measure the voltage at the input terminal; Check the photoelectric isolation module; Replace the board card for testing.

Output does not act

Check the output type (relay / transistor); Check the load wiring; Replace the board card.

Communication error

Clean the gold fingers of the back panel; Check the internal bus connection; Check for electromagnetic interference.
