The Allen-Bradley 1791-0B16 1791-OB16 is a 16 Output DC Block I/O Module designed for distributed control applications using Allen-Bradley Remote I/O networks. It provides 16 DC outputs arranged in two groups of eight, with a nominal 24 VDC output and an operating range of 10–30 VDC. Featuring fast output response, multiple RIO communication rates, and electrical isolation between power, I/O groups, and logic, the module provides reliable control of solenoids, relays, indicators, actuators, and other DC field devices. It is well suited for machinery, production lines, material handling, and existing PLC or SLC-based automation systems.
Compared with conventional distributed DC output modules, the Allen-Bradley 1791-0B16 1791-OB16 combines compact distributed I/O, flexible DC output control, direct Remote I/O connectivity, and reliable electrical protection for industrial automation applications.
