Modular Electronic Control Systems
Modular Controls
Description
The Johnson Controls/PENN System 450 Series is a small, versatile family of compact, multipurpose, digital electronic control, expansion, and power modules. System 450 modules provide accurate, reliable On/Off and analog control of temperature, pressure and humidity conditions for a wide variety of 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.
Features
- Durable, compact modular design with 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 applicationspecific 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
