Description

Product Overview

The Allen-Bradley 1794-OB16D is a Flex I/O digital DC output module designed with advanced diagnostic capabilities. It provides 16 current-sourcing outputs, each supporting up to 500mA, with a total module capacity of 8.0A. This module operates at a nominal output voltage of 24V DC and maintains a fast output signal delay of just 0.5 ms.

Engineered for efficient industrial automation, the 1794-OB16D detects, reports, and indicates open or shorted field devices. It allows hot-swapping on the terminal base without wiring changes, reducing downtime and improving system flexibility.
