Product Overview

The 1794-OB32P is an Allen-Bradley Flex I/O digitally protected 24 V DC sourcing output module within the Flex I/O platform. It provides thirty-two discrete outputs in two groups of sixteen and mounts on 1794-TB32 or 1794-TB32S terminal bases. It interfaces with PLC systems to drive DC loads such as pilot lights, solenoids, or relay coils under industrial automation control loops. Part number 1794-OB32P operates in standard ambient conditions typical of manufacturing and process environments.
