Programmable digital controller Alfanet 88

The ALFANET 88 is a control to operate electronic expansion valves. Emission takes place by means of a modulating pulse/pause control or a 0/10 Vdc P(I) signal. Valves of various makes and types can be used for this. Measured pressure, calculated temperature, measured temperature, temperature difference or emission percentage can be read in the display. The mode key enables you to select the readout you want to view.
