Installation Guidelines

• Mounting: Ensure the unit is securely seated on the CJ-series backplane. Lock the module using the sliders at the top and bottom to ensure a solid electrical connection.
• Wiring: Use the removable terminal block for field wiring. Ensure wires are properly crimped or secured to prevent loose connections in high-vibration environments.
• Commoning: Note that this unit uses 16 points per common. Ensure the common terminal is correctly wired to the 0V or 24V side of your power supply, depending on your PNP/NPN input sensor configuration.
• Safety: Always disconnect power to the PLC system before installing or removing any I/O modules to prevent electrical arcs or damage to the backplane communication pins.
