Transmitter supplied from the isolation amplifier

Our transmitter repeaters supply the feeder voltage for your transmitter.

2-wire transmitters regulate their own power consumption proportionate to the measured value; here the 4 - 20 mA connection provides the auxiliary energy for the transmitter and the level of the current is at the same time the output measured value.

3-wire transmitters usually have an active current output for the measured value and additionally terminals for the supply voltage (auxiliary energy).
