Specification

SEODescription

The Allen-Bradley 1769-OA8 is a high-performance Digital Output module designed for the CompactLogix 1769 series, providing 8 isolated sinking/sourcing outputs rated for 24V DC operation. This module integrates seamlessly with CompactLogix controllers via the embedded backplane, supporting direct connections to sensors, actuators, and other field devices in industrial automation systems. It operates within a 19.2–28.8V DC voltage range and functions reliably in temperatures from 0°C to 60°C. The 1769-OA8 Digital Output module is widely used in manufacturing, process control, and material handling industries due to its compact design, high-density I/O configuration, and robust performance in harsh environments. Key advantages include easy scalability, fault-tolerant wiring, and compatibility with Logix5000 programming. However, its 0.5A per-channel current limit may require additional relays for high-power applications. The CompactLogix 1769-OA8 Module ensures reliable integration with Rockwell Automation ecosystems, making it ideal for mid-sized control systems demanding precision and flexibility.
