6185 Loop-Powered Isolator

Brand: PR Electronics

  • 1-, 2- and 4-channel galvanic isolation
  • Slimline channel width of less than 6 mm
  • No separate supply necessary
  • Low response time
  • High noise suppression
Features
  • PR 6185 is powered by the measured signal and loads the loop with max. 1.8 VDC.
  • The input is protected against overvoltage and polarity error.
  • The drop voltage for each channel can be calculated according to the following expression: Vdrop = 1.8 + (Iout. * Rload.
  • The output is voltage-limited to 15 VDC.
  • Inputs and outputs are floating and galvanically separated.
