Supply Isolation Amplifier
AD-STV 24 GL


back to products

  Description

The supply isolation amplifier AD-STV 24 GL 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.

  Application

Supply of 2- or 3-wire transmitters like pressure or temperature transmitters and galvanic signal isolation.

  Specific characteristics

  • 3-way isolation of input, outtput and supply
  • Current transfer ratio 1:1, input = output
  • Integrated current-limited power supply
  •   Business data
