Isolation Transmitter for mA/V Signals with 2-wire Transmitter Supply

DA561 is specially designed for signal isolation and load amplification in the process industry.
A 2-wire transmitter can be connected to and supplied from the isolation amplifier. DA561 maintains a high isolation level (1,5 kV) between input and output. Current and voltage can be chosen independently as input and output signals.

  • Current and voltage input
  • Current and voltage output
  • Direct connection of 2-wire transmitter
  • Output test terminals
  • 1 500 V isolation level
  • Short response time
  • High noise immunity
  • Available for AC or DC power supply
  • DIN-rail mounting
  • Plug-in screw terminals
