Allen-Bradley 1791-IOVX is a 128-point, 24V DC Block I/O module that provides distributed I/O in a single unit, featuring 64 source input channels and 64 sink output channels. This high-density 1791 block is designed for Rockwell Automation systems and typically includes internal fusing to protect the 128 I/O points. In legacy configurations, the 1791-IOVX is used as a remote I/O block with PLC-2/PLC-3/PLC-5 and SLC-500 modular controllers for 24V field devices. The module wires for 24V DC operation as part of the 1791 Block I/O family to expand I/O capacity in an established automation scheme.
