The Allen‑Bradley 1746-OB32E is a 32‑channel DC digital output module for the SLC 500 family, designed to sit in a 1746 I/O rack and switch field loads from 10 to 30 V DC on each channel. This current‑sourcing module provides 32 electronically protected outputs with isolation between the controller side and field circuits rated up to 500 V DC, making it suitable for reliable DC load switching in a compact SLC 500 I/O setup. It’s a dedicated SLC 500 I/O module, backed by a standard Rockwell Automation warranty of 1 year.
