Allen-Bradley 1746-IM16 SLC 500 16-Channel Input Module

The Allen-Bradley 1746-IM16 is a 16-channel AC input module for the SLC 500 PLC system, designed to accept sixteen 200–240 VAC signals on discrete inputs. It installs in an SLC 500 I/O chassis via a Removable Terminal Block (RTB) and provides sixteen AC input points for wiring to field devices such as AC-powered sensors and switches in manufacturing and process automation. As part of the 1746 I/O family, the module communicates over the SLC backplane and is addressed as part of a 1746 I/O rack, enabling scalable monitoring of multiple AC inputs within Rockwell Automation control architectures. The 1746-IM16 is described as a 16-channel, 240 VAC input module within the SLC-500 product line.
