Installation Guidelines

• Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
• Handle the module using ESD-safe practices to prevent damage to sensitive internal components.
• Seat the module firmly into the designated slot in the SLC 500 rack and tighten the mounting screws to ensure proper backplane connection.
• Route analog signal wiring away from high-voltage AC lines and high-EMI sources to minimize signal noise and interference.
• Use shielded twisted-pair cabling for analog signals and ground the shield at one end to maintain signal integrity.

FAQ

What is the primary function of the 1746-NIO4I?

The 1746-NIO4I is an analog combination module for the SLC 500 system, allowing the controller to read analog inputs and provide analog outputs for control devices.

Is this module compatible with all SLC 500 racks?

The 1746-NIO4I is designed for standard SLC 500 I/O chassis. Please verify your specific chassis power supply capacity to ensure it can handle the 55mA (5V) and 145mA (24V) backplane current requirements.
