C450CPN-4C Johnson Controls Control Module

Overview

The Johnson Controls C450CPN-4C is a System 450 standard control module designed to provide reliable, digital electronic control over temperature, pressure, and humidity. It features a built-in LCD screen and a four-button touchpad user interface, offering a field-configurable out-of-the-box solution that replaces legacy System 350 and System 27 components. The module can operate as a stand-alone unit or connect seamlessly to expansion modules to control up to ten relay and proportional analog outputs.

Features

• Field-configurable out-of-the-box for quick installation
• Integrated backlit LCD and four-button touchpad user interface
• Provides one analog output supporting a self-selecting 0 to 10 VDC or 4 to 20 mA signal
• Modular plug-together design with 6-pin connectors eliminates the need for field wiring between modules
• Supports up to three input sensors and can expand to manage up to ten total outputs
