The Chromalox 50 Series Limit Controllers provide you with a comprehensive feature list and the flexibility to meet your most demanding process needs. This series is affordable, easy-to-use and adaptable to simplify all aspects of limit control.

This fail-safe protection device may be used to prevent damage to equipment or products. It will shut down a process when the preset parameter threshold is realized. The controller cannot be reset until the process has returned to an acceptable parameter condition.

The 50 Series Limit Controller maintains the maximum (High Limit Action) or minimum (Low Limit Action) process variable value since the last reset occurred. Additionally the controller records the accumulated time for which the limit has been exceeded since this parameter was last reset.

The 50 Series Limit Controllers are an ideal complement in both design and esthetics to its cousin, the Chromalox 40 Series Temperature/ Process Controllers.
