![System 450 is a family of modular, digital electronic controls that is easily assembled and set up to provide reliable temperature, pressure, and humidity control for a wide variety of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) and commercial/industrial process applications. The System 450 control system is designed to replace System 350 control system and System 27, and provide many additional features and benefits with less than a dozen model variations. All System 450 control modules are multipurpose and field configurable out-of-the-box; each module is designed for use in temperature, pressure, and humidity systems. A System 450 control system can be easily assembled and configured to monitor and control temperature, pressure, and humidity simultaneously. A single C450 control module can be set up as a stand-alone control or connected to expansion modules to control up to ten outputs based on any of the three available inputs. A control system may consist of relay outputs (Single-Pole, Double-Throw [SPDT]), analog outputs (010 VDC or 420 mA), or any combination of relay and analog outputs.TEMPERATURE, HUMIDITY,PRE](https://cdn11.bigcommerce.com/s-uhdhz/images/stencil/500x659/products/295947/927914/series338_picture_big_new__54519.1749573731.png?c=2 "System 450 is a family of modular, digital electronic controls that is easily assembled and set up to provide reliable temperature, pressure, and humidity control for a wide variety of Heating, Ventilating, Air Conditioning and Refrigeration (HVACR) and commercial/industrial process applications.
