The Allen-Bradley 1746-OB32 is a 32-channel DC output module for the SLC 500 PLC family, providing sourcing outputs to drive DC loads from 5 to 50 V. It offers 32 independent DC output channels designed for installation in a 1746 SLC rack with backplane, featuring isolation between the load circuits and the backplane up to 500 V DC. Typical uses include energizing relays, coils, and other low-power DC actuators in industrial automation where compact I/O expansion is required. Key specifications include 32 DC output points and a 5–50 V DC voltage range, tailored for the SLC 500 system’s digital output needs.
