Measuring transmitter MU 1000Voltage - current - resistance - RTD - thermocoupleFeaturesM DC voltage/current/resistanceM AC voltage/currentM Temperature RTD (Pt100, Pt1000, Ni1000)Thermo couple J,K,S(built-in cold junction compansation)M Accuracy 0.2 %M Analog output signal0/4 ... 20 mA and 0 ... 10 VM Current burden max. 500 ΩM Full 3-port isolationM Power-on LEDM Standard case for Wall mounting andTS 35 DIN railGeneral informationThe MU1000 measuring transmitter converts physical signals to industry standard signals 0/4...20 mA and0...10 V. The electrical isolation between input and output prevents ground loops and associated problems. Aninputfilter prevents interferences which are overlayed at the measuring signal.Short informationAdjustmentOutputStart value and end value can be adjusted with 2 trim pots at the front plate.Current and voltage output can be used simultaneous. Changing the current output from0...20 mA to 4...20 mA is switch selectable.- 1 -
