Application

  • Galvanic separation of analog current signals.
  • Elimination of ground loops and measurement of floating signals.
  • A competitive choice in terms of both price and technology for galvanic isolation of current signals to SCADA systems or PLC equipment.
  • Especially useful in applications necessitating an unproblematic transmission of current signals according to NAMUR (sensor error detection).

Technical characteristics

  • 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.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighboring units, up to 168 channels can be mounted per meter.
