The Allen-Bradley 1746-IO12 is a versatile combination I/O module for the SLC 500 platform. This module is designed to save valuable chassis space by integrating both digital inputs and relay outputs into a single unit. It features six 24V DC sink inputs for monitoring sensors and other field devices, and six individually isolated relay outputs for controlling a wide range of AC or DC loads. Its robust design and reliability make it an ideal choice for various industrial automation applications where both input monitoring and output control are required in a compact form factor.
