Allen-Bradley 1746-LA16 is a 16-channel input module for the SLC 500 controller family. It plugs into a 1746 I/O rack and communicates with the associated SLC 500 processor through the backplane, providing 16 discrete input points for digital signals from field devices such as switches and sensors. This module is part of the 1746 SLC I/O lineup, enabling compact, centralized input acquisition in industrial automation projects.
