Description : Single stage controller for temperature - DR 983
The DR 983 C controllers are devices suitable for applications on normal temperature refrigerating units. They are provided with a PTC thermostatic probe input (NTC can be selected by parameter) and a relay output for compressor management. Defrost cycles are controlled at time intervals by stopping the compressor. The value of the probe’s reading is viewed on a display with three digits and a minus sign. All versions are provided with a TTL connection in order to use Copy Card, the quick programming accessory. These controllers are available in theRail Din standard format with a 230 Vca supply voltage.
