AD-STV 300 GS

Description

The universal supply isolating amplifier AD-STV 300 GS converts the two active standard industrial signals 0...20 mA and 4...20 mA, amplifies them and separates them galvanically. In addition, the device still has a current-limited supply voltage for the supply of two-wire transmitters. The signals are also available at the output. All combinations are possible. A switchover is not necessary. The signal combination from input to output is selected via the terminals.

AD-STV 300 GS

Application

Amplification and adaptation of standard active signals and transmitter signals with easy conversion to a freely selectable output signal.

Specific characteristics

  • Three signals freely selectable at the input and output
  • current limited supply voltage of transmitters
  • Galvanic isolation and amplification
  • No mechanical switches necessary
  • Input / output combination by clamping the desired signals
  • No subsequent adjustment necessary
  • Suppression of live zero signal (4mA)
  • Price / performance ratio allows for warehousing
