The Allen-Bradley 1756-OA8E is a high-performance ControlLogix AC output module engineered for demanding industrial environments. This 8-point isolated output module operates at 120/240V AC, delivering 2A per point with a total current capacity of 8A per module. Designed for robust control of solenoids, relays, motors, and other AC loads, the 1756-OA8E features electronic fusing per channel to prevent overcurrent damage, along with real-time diagnostics via the ControlLogix backplane. Its hot-swappable capability allows replacement without powering down the chassis, critical for continuous process operations. The module supports standard ControlLogix 1756 I/O chassis and is ideal for applications in manufacturing, oil and gas, and power generation where reliable AC output switching is essential.
