EX isolated amplifier, auxiliary voltage and HART® communication as option
The isolated amplifier WG 21 supplies the intrinsically safe monitor with auxiliary energy and transfers the measured value. Can be integrated into the IQ SENSOR NET:
The isolated amplifier is installed outside the zone and supplies the monitor within the zone with ist own intrinsic power circuit. In addition, it transfers the meaured value via an mA output or via HART (optional). The WG 21 is also available with a 24 V AC/DC auxiliary voltage and can therefore be integrated into the IQ SENSOR NET.
