The 1756-OA8E is a ControlLogix digital AC output module featuring 8 electronic fused outputs arranged in groups of 4. Designed for high-density control applications, it operates across a broad voltage range of 74 to 265V AC at 47 to 63 Hz. The module delivers up to 2.0A per output point (up to 4.0A max per group) and includes integrated electronic fusing to protect individual output points and connected field loads against overcurrent conditions. It provides 125V continuous basic isolation between output groups and utilizes a removable terminal block (RTB) interface for field wiring.
