System 450 Control System with Control, Power and Expansion Modules System 450™ Series Modular 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 HVACR applications, commercial process applications, and industrial process applications. The System 450 control system is designed to replace System 350™ and System 27 control systems, and to provide many additional features and benefits with fewer than twenty model variations. System 450 control modules...

The System 450 Series is a family of compact digital electronic control, expansion, and power modules that are easily assembled and set up to provide reliable on/off and proportional control of temperature, pressure, and humidity conditions in a wide variety of HVACR applications, commercial process applications, and industrial process applications. A System 450 Series control system includes: • A single System 450 Control module with LCD and four-button touchpad • One to three inputs • One to ten relay and/or analog outputs (provided by the control module and expansion modules) • An...

System 450 Control modules with Ethernet Communications allow you to: ■ Directly connect your computer to the System 450 control module with an Ethernet cable, then set up, monitor, and modify your control system. ■ Connect your control system to an existing network and establish a static IP address or use a DHCP server to provide a dynamic address. ■ Set up a Dynamic DNS and allow you to browse to your System 450 control system on a local network or across the Internet using a text-based URL (host name) instead of a numeric IP address and port number. The System 450 web Ul offers easy...

Proportional Plus Integral Control In addition to standard proportional (only) control analog signals, a System 450 control system provides integral control capability and six-time-integral selections that enable you to set up analog outputs to generate a proportional plus integral signal. Proportional plus integral (PI) control incorporates a time-integral control action with proportional control action. Therefore, if properly set up, a PI control loop can effectively eliminate offset error and enable a controlled system to drive much closer to the desired setpoint, even under large...

Overview Run-Time Balancing The reset control module's run-time balancing feature enables your control system to even out the runtimes of staged equipment by automatically selecting the stage with the least runtime when responding to increases in the system load. Run-time balancing allows control of up to four staged outputs. See the table on page IX for more information about the System 450 control modules with this feature. Analog Output Signal Limiting The Output Signal Update Rate and Output Deadband features on the control modules with communications are used to reduce the rate at...

The System 450 control module is the supervisor of your control system and the interface for the systems inputs, supply power, and outputs. The photo below shows an example of an available System 450 control module. All System 450 control systems require a control module for setting up the control system's inputs and outputs, monitoring the control system's status, and controlling the system's outputs. System 450 control modules are capable of monitoring up to three inputs and controlling up to ten outputs that can be any combination of relay and analog outputs (provided by expansion...

System 450 Hybrid Analog Output Control Modules A System 450 Hybrid Analog Output Control Module can provide the same types of control as the standard controls, while providing a hybrid analog output control option for your application equipment. The hybrid C450CPW-100 analog output control feature enables an analog VDC output to transition to a pulse output at low signal levels. This provides more efficient low-speed control of electronically commutated (EC) variable speed motors. These EC variable speed motors are typically used in condenser fan applications on a wide variety of...

System 450 Compatible Sensors and Transducers System 450 control modules are designed to operate with a variety of compatible sensors and transducers. The System 450 compatible sensors and transducers cover a wide range of temperature, pressure, and humidity conditions. System 450 compatible sensors and transducers come in a variety of styles and configurations, allowing you to select the sensor or transducer that best fits your control system requirements. For ease of installation and setup, the sensor or transducer type selected in the UI automatically determines the sensed condition,...
