The N321 temperature controller is used to measure, indicate and control temperature in many different systems. It accepts 4 different sensors types: Pt100, NTC or Thermocouple J. The user can program the control action according to the application: direct action (refrigeration) or reverse action (heating).   The internal 10 A relay can directly switch compressors or electrical heaters with an ON/OFF control.
