Allen-Bradley 1746-N14 SLC 500 Analog Input Module

The Allen-Bradley 1746-N14 SLC 500 High-Resolution Analog Input Module (Series B) brings four analog input channels to an SLC 500 rack, converting sensor signals into the PLC. Each channel can be configured by the user for either voltage or current input, enabling a single module to accommodate diverse sensors and signal conditioners without cross-wiring. As part of the SLC 500 analog I/O family, the 1746-N14 communicates with the processor over the 1746 backplane, using the standard I/O addressing scheme used by SLC 500 systems. This four-channel card is designed for compact automation layouts where high-resolution inputs are needed in a small footprint, making it suitable for process monitoring, data acquisition, and general analog sensing tasks in industrial environments. The Series B designation indicates a later revision in the module lineup, aligning with Rockwell Automation’s aging SLC 500 ecosystem and offering a dependable path for maintaining legacy control systems.
