DC24D

DC24D

Universal controller

DIN rail housing, display, 230 VAC power supply, 4 relays, 2 analog outputs, 5 PT1000 inputs, 1 0-10 V input, 1 4-20 mA input, 2 digital inputs, bus interface, clock, plug-in terminals.

The DC24D module is a universal controller that performs measurement, monitoring and control functions for the following applications

• control of cooling units (MT and LT refrigeration) with thermostatic expansion valve,
• compressor control,
• condenser control,
• hygrometry control,
• gas concentration control,
• management of air conditioning and lighting zones,
• input-output mode.

The module is mounted on DIN rails.

The DC24D module can be programmed from the Teleswin supervision software or directly from the keys on the front panel. The integrated display shows the values measured by the connected sensors and is used for programming the parameters.
