The Allen-Bradley 1746-1B16 Series C DC Input Module for the SLC 500 is a 16-channel digital input interface that accepts 24 V DC signals from field devices and reports their on/off status to the controller. Designed for plug-in installation on the 1746 backplane, it provides sixteen inputs that you can wire to sensors such as pushbuttons, limit switches, and proximity sensors, enabling reliable state monitoring across industrial equipment. As part of Rockwell’s SLC 500 I/O family, the 1746-1B16 integrates with the backplane I/O architecture and supports the standard 24 V DC input range used by DC input modules in this platform.
