Current- and Voltage Transmitter CVT 500Measuring input DC- and sinusoidal AC-signalsFeaturesM Arithmetic average value measurement,RMS calibrated or DCM Output 0/4 ... 20 mA or 0/2 ... 10 V DC switchselectableM Span adjustable ±5 %M Full 3-port isolationM Supply voltage 230 V ACor 24 V DCM Power on LEDM 22.5 mm case for DIN rail mountingGeneral informationTransmitter CVT 500 convert current or voltage signals to proportional industry standard signal 0/4...20 mA;0/2...10 V DC. Direct measurement of currents up to 5 A and voltages up to 400 V are possible.Short informationOutputAC / DCThe output is switch selectable on the front panel between 0/4...20m A or 0/2...10 V. For currentoutput a link from terminal 8 to 9 must be connected.The input signal can be changed from AC to DC by DIP-switch on the front panel.- 1 -
