MODULAR ELECTRONIC CONTROLS
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 ( 0 – 10 VDC or 4 – 20 mA ), or any combination of relay and analog outputs .
