1746-NI16I Here's a breakdown of its key features:

Input Channels: The module has 16 analog input channels. Each channel can accept a voltage or current input signal.

Signal Types: The module supports both voltage (0-10V DC) and current (4-20mA) input signals.

Resolution: It provides a resolution of 16 bits, which allows for precise measurements of analog input values.

Configuration: The setup and configuration of the module are typically done through software programming using the RSLogix 500 programming tool provided by Rockwell Automation.

Compatibility: The 1746-NI16I module is compatible with the SLC 500 series PLCs, including the SLC 5/03, SLC 5/04, and SLC 5/05 models.

Communication: The module communicates with the SLC 500 PLC processor via the backplane, allowing the PLC to read analog input values and incorporate them into control and monitoring routines.
