Product Overview

The Allen-Bradley 1756-OB32 is a 32-point digital output module designed for the ControlLogix system, providing reliable and precise control of actuators, relays, and indicators in industrial automation applications. It supports both sourcing and sinking outputs over a 10–31.2V DC range, offering versatility for a wide variety of devices.

This module features individual channel protection to prevent a single-point failure from affecting the entire system, ensuring robust performance in manufacturing, packaging, and material handling operations. It integrates Producer/Consumer communication technology, enabling output status sharing across multiple controllers for coordinated system control.

Compact and efficient, the 1756-OB32 dissipates a maximum of 4.8W at 60°C and draws 300mA from the backplane. Standard removable terminal blocks simplify wiring and maintenance, while built-in diagnostics provide real-time load monitoring. Its wide voltage tolerance and durable design ensure reliable operation in temperature-variable industrial environments.

The Allen-Bradley 1756-OB32 module seamlessly integrates with analog and specialty I/O modules, delivering a comprehensive solution for complex automation systems that demand high-speed performance and precision control.
