Modular controls

May 25, 2009

Johnson Controls, Inc. is now offering the System 450™ Series of microprocessor-based modular controls. As a new product within the Johnson Controls/PENN brand, the System 450 Series provides versatile, compact, cost-effective and accurate digital control for a variety of HVAC controls applications.

With nine model variations – each designed to be multi-purpose, adaptable and field configurable – the System 450 Series can monitor and control temperature, pressure and humidity simultaneously. The enhanced design creates a versatile and durable custom control system that allows the user to monitor and control multiple control loops.

Designed to replace the System 350 and System 27 Series control systems, the new System 450 Series is built to be easy to use, flexible, and to handle hundreds of custom applications. These applications include heating and/or cooling control, boiler temperature reset, fan control, floating pressure of an actuator and humidification/dehumidification control.

This new product is released as Johnson Controls celebrates the 90-year anniversary of the PENN brand. Two brothers, Albert and Ralph Penn, founded the refrigeration products business on December 1, 1919.
