XM20 device allows to read an analogical voltage continuous signal up to 1000 V DC and to turn it into a pulsed 0-5 Hz signal compatible with the standard of input signals for CM2 SOLAR -or XRWU GOLD/X-METER platforms-. Guaranteed accuracy to 0.5% in full-scale output. The main feature of this device, besides its extremely contained dimensions of just one DIN module, is the presence of an internal galvanic insulation equivalent to 4kV between the measuring field circuit and the pulsed output circuit.
