Process Controllers

The SERIES 32B, 16B, 8B, & 4B Temperature/Process Loop Controllers offer advanced control features for the most demanding temperature or process applications. Offered in 4 standard DIN cutout housing sizes, these controllers are designed with dual, 4 digit LED displays for local indication of the process value, set point, and output conditions.

FEATURES/BENEFITS

• Universal input accepts process transmitters, RTD’s or thermocouple signals

• On/off, PID, or manual output control

• RS-485 standard on all models

• Stage control program for up to 64 ramp/soak actions

APPLICATIONS

• Oven, boiler, or chiller control

• Environmental chambers

• Hot plates/melt pots

• Medical equipment

• Packaging equipment

• Food service equipment
