A-B 1756-CMS1B4 ControlLogix Communication Module

Allen-Bradley 1756-CMS1B4 ControlLogix Communication Module

Product Description

The Allen-Bradley 1756-CMS1B4 is a ControlLogix Compute Module designed for integration into the ControlLogix 1756 chassis system. Unlike traditional communication modules, it provides an embedded computing environment that can run custom applications and exchange data directly with ControlLogix controllers through the chassis backplane.

The module is suitable for edge computing, data processing, custom software applications, and industrial automation systems requiring additional computing capability.
