The ALLEN-BRADLEY 1769-OF8C OUTPUT MODULE is a critical component in modern CompactLogix-based automation systems, engineered to deliver precise analog current outputs for process control applications. This 8-channel module provides isolated 0-20 mA or 4-20 mA signals with 16-bit resolution per channel, making it ideal for driving actuators, valves, and other field devices that require accurate current loop control. Each channel features individual open-circuit and short-circuit detection, enabling proactive maintenance and minimizing downtime. The module communicates seamlessly via the 1769 backplane, supporting high-speed data exchange with the controller. With its rugged construction and wide operating temperature range, the 1769-OF8C is built to withstand demanding industrial environments. Below is the detailed specification table.
