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.
Application
Supply of a transmitter in the hazardous area and galvanic isolation of the signal.
Specific characteristics
– Supply of a transmitter up to zone 0 (gas) or 20 (dust)
– Active current output, current sink output and voltage output
– Open-circuit detection according to Namur recommendation NE43
– Further parameters configurable via configuration software AD-Studio
– Detachable, coded connection terminals
– Zero and full scale adjustment possible via front panel keys
