990 Temperature Control

The 990 Temperature Control series consists of Barber-Colman System 990 controllers, a family of 1/4 DIN temperature controllers built for industrial process control applications. These units monitor temperature through thermocouple or RTD inputs and regulate heating or cooling equipment to maintain a target setpoint.

Models across the series offer PID control, programmable dual outputs, alarm functionality, and digital temperature display. The range spans numerous configurations, identifiable by their 9E-prefix part numbers, to suit different input types and output requirements.

Common Applications

System 990 controllers are widely used in paper manufacturing, plastics processing, and other industries requiring precise thermal management of process equipment.
