The universal conception ofthe multipurpose input allows indication of all physical dimensions, which can be converted to 0/4...20 mA,0/2...10 V DC. The display range can be adjusted without an external signal source. Other models of the<strong>DP4824A</strong> are for temperature measurement with Pt100 and Pt1000 sensors. The input-configuration is switchselectable from the side, without opening the case.Input and supply voltage are isolated.- 1 -
