C450CPW-400C Johnson Controls Control Module

Overview

The Johnson Controls C450CPW-400C is a professional-grade System 450 control module designed to provide reliable sensing and operating control for HVACR and commercial or industrial process applications. Featuring a backlit LCD and a four-button touchpad user interface, this hybrid analog output control module is engineered to optimize and extend the controlled speed range of variable-speed electronically commutated (EC) motors. It allows for custom configurations to monitor multiple conditions simultaneously.
