Description : Single stage controller for temperature - DR 4020 R 12-230 V
DR4020 controllers are devices with two point of intervention and can be used to control temperature(EWDR 4000/T), relative humidity (EWDR 4000/R), and pressure (EWDR 4000/P). According to the model, they are provided with an input for thermostatic probes (PTC, Ni100,Pt100, TcJ, TcK, 4…20 mA current), humidity probes (EWHS 280/300/310) or pressure probes (EWPA 007/030). The value of the probe’s reading is viewed on a three–digit display. The controllers are available in the 4 DIN modules standard format and the power supply voltage can be 230, 115, 24 Va, 18…36 Va, 24…48 Vc, 12 Va/c.
