Installation Guidelines

Mounting: Secure the CJ1W-IA111 to the CJ-series backplane. Ensure the locking mechanisms at the top and bottom of the unit are fully engaged to establish a secure electrical connection with the PLC bus.
Wiring: The removable terminal block allows for field wiring to be prepared and managed easily. When handling 100–120 VAC, ensure proper insulation and wire labeling according to safety standards.
Commoning: All 16 inputs share a single common. Ensure the AC neutral or hot leg connected to the common terminal aligns with the specific requirements of your field devices.
Safety: Always de-energize the AC field supply and the PLC power before connecting or disconnecting the terminal block to prevent accidental contact with hazardous voltages.
