Model AD-STVEX 710 GVD - Isolation Amplifier Brochure

The supply isolation amplifier AD-STVEX 710 GVD is designed for operation of an intrinsically safe 2-wire measuring transducer (transmitter) and an mA current source installed in the hazardous area / potentially explosive atmosphere.A 2-wire measuring transducer is supplied with power and the impressed analog 4-20 mA measuring signal is galvanically isolated and transmitted from the hazardous area /potentially explosive atmosphere to the non-hazardous area. Alternatively, the passive input current circuit of the supply isolation amplifier detects the 0/4-20 mA measuring signal from a current source from the hazardous area / potentially explosive atmosphere and isolates it galvanically to make it available at the output of the device in the non-hazardous area. In this case, AD-STVEX 710 GVD operates as an isolation amplifier. The device features a universal mains supply unit so it can be used with various supply voltages.
