AD-STV 24 GVB

Description

The supply isolation amplifier AD-STV 24 GVB serves the galvanic isolation and amplification of current signals in the range 0/4...20 mA. The transmitter is supplied by an isolated and limited supply voltage. Input, output and power supply are galvanically isolated. An integral, electronic power pack is designed with a voltage range of 11 to 30 VDC, also for 12V battery voltage. In combination with the small shape, high packing densities can be achieved.

AD-STV 24 GVB

Application

Supply of 2-wire transmitters like pressure or temperature transmitters and galvanic signal isolation.

Specific characteristics

3-way isolation of input, output and supply
Current transfer ratio 1:1, input = output
Integrated current-limited power supply
Suitable for battery voltage of 12VDC
