Description

The 1791-IOVX is a discontinued high-density Block I/O module manufactured by Allen-Bradley for the Block I/O system family. Operating on a 24 VDC power supply, this integrated unit provides a total capacity of 128 discrete I/O channels, featuring 64 sourcing input channels and 64 sinking output channels in a single self-contained housing.

High-Density Signal Handling and Power

Designed for centralized control cabinet layouts requiring high channel counts, the module processes up to 64 24 VDC sourcing inputs alongside 64 24 VDC sinking outputs. The self-contained Block I/O construction integrates power conversion, terminal connection blocks, and local status indicators, reducing required DIN-rail footprint and inter-module wiring complexity.

Controller Compatibility and Integration

The module communicates over standard Allen-Bradley Remote I/O (RIO) networks, interfacing directly with legacy controller platforms. It provides native network compatibility with Allen-Bradley PLC-2, PLC-3, and PLC-5 programmable logic controllers, as well as SLC 500 modular controller systems equipped with remote I/O scanner modules.
