Description : Two stage controller for temperature - EW7221 UNIVERSEL 12-230 V
The EW72 controllers (72x72) are devices with 2 relay or 2 points of intervention only with ON/OFF, PD, PID actions and SOFT START function; they can be used for temperature, relative humidity and pressure control. 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 double display one for on 4 digits and the second (for set point); the power supply switching on 12...24V at 95...240V.
