Superheat controller with management of PWM electronic expansion valve

Superheat controller with management of PWM electronic expansion valve

DIN rail housing, display, 230 VAC power supply, 3 relays, 1 valve output (triac) 24-240 VAC, 1 analogue output, 5 PT1000 inputs, 1 pressure sensor input, 1 0-10 V input, 1 4-20 mA input, 2 digital inputs, bus interface, clock, plug-in terminal blocks.

Compatible with all major pulse width modulated electronic expansion valves on the market (e.g. Danfoss AKV).

The DC24DE module is a universal controller that performs measurement, monitoring and control functions for the following applications:

– control of cooling units or cold rooms (MT and LT refrigeration) with superheat control using electronic expansion valves,
– compressor control,
– condenser management,
– humidity control,
– management of air conditioning and lighting zones,
– input-output mode.

The module is mounted on DIN rails.

The DC24DE module can be programmed using the Teleswin supervision software or directly via the buttons on the front panel. The integrated display shows the values measured by the connected sensors and is used for programming the parameters.
