Series 32B

1/32 DIN Temperature/ Process Controller

Universal Input, Dual Temperature Output Control, RS-485 Communication

The compact Series 32B Temperature/Process Controller offers advanced control features for the most demanding temperature or

process applications. Enclosed in a 1/32 DIN housing, the Series 32B is designed with dual, 4-digit LED displays for local indication

of process value and setpoint. Control methods include ON/OFF, PID, self-tune, and manual tune. PID control is supported with 64

temperature and time (ramp/soak) control actions. The dual loop output control allows simultaneous heating and cooling control.

The second output can be configured as an alarm mode using one of the thirteen built-in alarm functions.

RS-485 communication is standard on the Series 32B. Up to 247 communication addresses are available with transmission speeds of

2400 to 38,400 bps. The controller also features universal input, selectable temperature units (^๐F/^๐C), selectable resolution, quick

sampling rate and security protection.
