INTRODUCTION
The features of the DES2000 controller include:

PID Tuning

Display can show process variable or setpoint during normal operation

Solid state output to operate a solid state relay
The DES2000 controller is a microprocessor-based digital control instrument. The
instrument can be configured as a proportional controller. Initially the CONTROL will
allow the heater to operate at full power. However, as the actual oven temperature
reaches the setpoint, the Proportional Control will cycle the heater on and off,
minimizing process temperature fluctuations.
