Allen Bradley 1756-OA16I Digital Output Module

The AB 1756-OA16I is a high-voltage AC digital output module for ControlLogix systems, providing 16 isolated triac outputs rated for 74–265 VAC operation. Designed to control actuators, solenoids, and relays in high-voltage applications, the module supports up to 5A total output current and uses plug-in 36-pin terminal connections for efficient wiring.

With individually isolated outputs and support for standard 120/240V AC loads, the 1756-OA16I is ideal for robust industrial control systems requiring reliable and noise-immune AC switching. It installs into any 1756 chassis and integrates seamlessly with Logix-based controllers.
