AD-STVEX 710 GVD

Description

The AD-STVEX 710 GVD supply isolating amplifier is used for the intrinsically safe supply of a transmitter installed in the hazardous area. The supply isolation amplifier itself is installed as associated electrical equipment in the non-hazardous area, i.e. the safe area. The signal is galvanically isolated and transmitted to the non-hazardous area. The passive input also allows active signals from the hazardous area. The active current output, the current sink output and the voltage output facilitate the adaptation to the following signal input. The device can be operated at 24 V DC or 230 V AC.

AD-STVEX 710 GVD

Application

Supply of a transmitter in the hazardous area and galvanic isolation of the signal.
