Controller for refrigerating units with frequency/voltage output to control compressor inverters
Electronic controller for refrigeration applications with PID or ON/OFF control and defrost control at programmed times (Real Time Clock) or at time intervals. The instrument has a frequency modulated or analogue digital output, up to 4 relay outputs, up to 4 inputs for temperature probes and 2 digital inputs.
It can also be equipped with an RS485 communication interface and a clock-calendar which allows the activation of HACCP functions for storing the last 10 alarms that have occurred.
Parameters programming and their visuaslization can be done through an external panel 78×35 (P34) which communicates via the LIN network or, in the lack of this, it’s possible to use dip switches placed on the rear side of the instrument.
