AD-STV 22 GVB

Description

The supply isolation amplifier AD-STV 22 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. The electronic wide range power supply avoids an excessive heating. In combination with the small shape, high packing densities can be achieved.

AD-STV 22 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
