WG A7 21 Isolated amplifier 德国WTW的产品资料如下：
Isolated amplifier WG 21 A7
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
Highest safety, even at high ambient temperatures
Safe separation and isolation of input, output and auxiliary power
Can be connected to the IQ Sensor Net
The isolated amplifier is installed outside the zone and supplies the monitor within the zone with its 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 .
