Specification

The 1756-OX8I is a premium isolated AC output module within the Allen-Bradley ControlLogix family, engineered for demanding applications requiring robust signal isolation and high channel density. Each of the 8 output points is optically isolated from the backplane and from each other, ensuring superior noise immunity and protecting the controller from voltage spikes. This module is ideal for switching solenoids, contactors, indicators, and small motors in environments where electrical isolation is critical. The 1756-OX8I supports a wide voltage range of 24-140V AC/DC per channel, with a continuous current rating of 2A (up to 10A per module total). It features a screw-type terminal block for secure wiring and is fully compatible with all ControlLogix chassis and controllers. For reliability, it includes diagnostic indicators for each channel and is designed for hot-swappable operation without powering down the system.
