Features:
- SLC 500 Analog I/O Module
- This module is a single-slot module
- Sixteen (16) Inputs configurable for 0 to 20 mA, 4 to 20 mA, ±20 mA, and 0 to 1 mA
The Allen Bradley 1746-NI16I is a 16-bit resolution, 16-channel analog input module. The module operates with a current range of -20 to 20 mA. Its backplane current is 125 mA at 5 V and 75 mA at 24 V. Maximum backplane power dissipation is 2.425 watts (0.625 watts at 5 V DC and 1.8 watts at 24 V DC). The common-mode voltage relative to the analog common terminal is +/- 10.25 volts.
The module has a heat dissipation of 2.43 watts and uses a 25-pin D-type AIFM connector. When installing the module into the chassis, it is not necessary to remove the terminal blocks on the module. However, if the terminal blocks are removed, please use the label next to the terminal blocks to identify the module's location and type.
The 1746-NI16I Allen Bradley SLC 500 Analog I/O Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Analog inputs are used to connect analog process variables to measure their amplitude. They are primarily used for monitoring or as feedback signals in closed-loop control systems to enable manual or automatic control, typically employing a proportional-integral-derivative (PID) control algorithm. Without this feedback signal, automatic control cannot be fully realized.
This module supports multiple data formats, including engineering units (EU), PID proportional data, and proportional counter data, and can be configured via RSLogix 500 software. Furthermore, it features open-circuit detection to identify sensor or wiring faults.
Product Lifecycle Notes: As of September 30, 2024, Rockwell Automation has officially discontinued production of the 1746-NI16I. While some inventory may still exist, we recommend that users planning to migrate to newer platforms such as the CompactLogix or ControlLogix series discontinue production as soon as possible.
