Product Details

Description · Specifications · Product Overview

Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.

The 1756-OW16IK is a ControlLogix family module providing sixteen isolated normally-open relay outputs via a 36-pin interface. Designed for integration into Allen-Bradley ControlLogix systems, it handles both DC and AC loads across a wide voltage range and supports time-synchronized operations. Controls engineers and maintenance professionals use this module for switching discrete loads in industrial applications such as motor control, signal-driven valves or lighting systems, and applications requiring isolation between PLC backplane and field circuits.
