Allen Bradley 1756-OW16I | ControlLogix 16-Channel Isolated Digital Output Module

Product Description

The Allen Bradley 1756-OW16I is a ControlLogix discrete output module designed to provide sixteen individually isolated channels. Each channel uses normally open (N.O.) contacts, supporting both AC and DC voltage ranges for flexible application in industrial automation. With robust current ratings, low signal delay, and removable terminal block options, the module ensures reliable switching performance across diverse control environments.
