Product Overview

The 1756-OC8 is a ControlLogix DC output module from Allen-Bradley, providing eight discrete output channels (configured as two groups of four). It operates on a 48 V DC source with an allowable input range of 30…60 V DC. It belongs to the ControlLogix I/O family and is typically used in discrete control applications-such as actuator control or motor relay switching-in industrial automation systems.
