The System 450 Series Modular Controls are the next generation of Johnson Controls/ PENN® digital electronic control, expansion, and power modules designed to provide accurate, cost-effective, compact, custom control systems for a wide variety of Heating, Ventilation, Air Conditioning, 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 modules are multipurpose and field configurable out-of-the-box; each module is designed for use in temperature, pressure, and humidity systems. In fact, a System 450 control system can be easily assembled and configured to monitor and control temperature, pressure, and humidity simultaneously. A single System 450 control module can be set up as a stand-alone control or connected to expansion modules to control up to 10 outputs based on the input from up to 3 control sensors. A control system's outputs can be relay outputs (On/Off), analog outputs (0-10 VDC or 4-20 mA), or any combination of relay and analog outputs.

  • plug-together connectors and DIN rail or direct wall mount capability eliminates field wiring between modules and allows you to quickly and easily assemble, install, and upgrade your System 450 control systems
  • Multi-purpose, field-configurable modules designed for global use enable you to design and configure a wide variety of custom control systems capable of controlling temperature, pressure and humidity (simultaneously), with only a handful of models
  • Backlit Liquid Crystal Display (LCD) and four-button touch pad User Interface (UI) provides quick, clear, visual status of the control system's input sensors and outputs with the touch of a button and enable you to quickly and easily set up and adjust the sensors and outputs in the field
  • Up to three input sensors and up to ten outputs (relay or analog) - allow you to build both simple and complex application specific control systems and reduce your costs to only the required components
  • Versatile, all-in-one, stand-alone control modules - provide multipurpose On/Off or analog controls (depending on the model) that are temperature, pressure, and humidity capable out-of-the-box and field configurable to replace a wide variety of HVACR controls
  • An extensive suite of compatible temperature, pressure, and humidity control sensors - cover a wide range of temperature, pressure (air and refrigerant), and humidity conditions in standard units of measurement for global markets
  • Range:-40° to 250°F; 10 to 95% RH; 0 to 750 psi
  • Differential Range: 1° to 30°F; 2 to 10% RH
  • 2 to 50 psi or 10 to 100 psi
