The System 450™ is a family of modular, digital electronic controls that you can assemble and set up to provide reliable temperature, pressure, and humidity control for a wide variety of HVAC, commercial, and industrial process applications.

The System 450 control system replaces the System 350™ and System 27 control systems, and provides additional features and benefits with fewer than 20 model variations. The System 450 control modules provide a field-configurable out-of-the-box solution. Most System 450 control modules can control temperature, pressure, and humidity systems simultaneously.

You can set up a single C450 control module as a stand-alone control or to connect with expansion modules to control up to 10 On/Off relay and proportional analog outputs, based on any of the three available inputs.

Use the System 450 control modules with communications to connect System 450 control systems to Modbus® or Ethernet networks for remote monitoring and setup. The Modbus communications control module is an RS485, rooftop unit (RTU) compliant subordinate device. The Ethernet communications control module has an integral web server that can deliver web pages through a direct connection, on your LAN, or across the internet.

The System 450 reset control modules provide many of the features of the standard models for temperature and humidity control. In addition, these modules provide setpoint reset, real-time setback scheduling, and equal run-time balancing capability.

The System 450 control module with hybrid analog output has a single self-selecting analog output to optimize and extend the controlled speed range of variable speed electronically commutated (EC) motors.
