The Allen-Bradley 1791-0B32 / 1791-OB32 is a 32 Output DC Block I/O Module designed for distributed control applications using the Allen-Bradley Remote I/O (RIO) network. It provides 32 DC outputs arranged in four groups of eight, with a nominal 24 VDC output and support for multiple RIO communication rates. Featuring fast output response, electrical isolation between I/O groups and logic, and individual output status indication, the module provides reliable control of solenoids, relays, indicators, actuators, and other DC field devices. Its block I/O architecture makes it well suited for machinery, manufacturing lines, material handling, and legacy PLC-based automation systems.
Compared with conventional distributed DC output modules, the Allen-Bradley 1791-0B32 / 1791-OB32 combines high output density, direct Remote I/O connectivity, fast switching, and reliable electrical isolation for industrial control applications.
