Allen-Bradley 1791-IOBX I/O Module with Built-in Power

Product Overview

The 1791-IOBX from Allen-Bradley is a versatile 1791 Block I/O Module that integrates a built-in power supply and interface for DC-powered applications. It provides 64 sinking inputs and 64 sourcing outputs, making it ideal for compact industrial automation systems.

This module combines the functionality of an I/O module, I/O rack, adapter, and power supply into a single unit. Connections are made through removable terminal blocks mounted on the sides, while an additional non-removable terminal block connects to external 24V DC power.

1791-IOBX includes LED indicators for Power, Active, Communication, and Fuses, along with pushbuttons for selecting input or output displays. Configuration switches allow users to set I/O groups, rack address, transmission rate, and processor restart lockout.

Engineered for high efficiency, the module supports reliable operation with robust signal conditioning and protection circuitry, ensuring optimal performance in demanding industrial environments.
