参数
包装
  • 1 Channel (DRSL-LPI-1) or 2 Channel (DRSL-LPI-2) Input Loop Powered Isolators
  • Powered by the Analog Input Current Signal Loop
  • 1:1 Signal Ratio
  • Low Input Voltage Drop
  • Fast Response Time <5 ms
  • High Conversion Accuracy, <0.1% of Span (0 to 20.5 mA)
  • Slimline 6 mm (0.24") Housing

  • The DRSL-LPI Series DIN rail inputloop powered isolators provide acompetitive choice in terms of bothprice and technology for galvanicisolation of current signals toSCADA systems or PLC equipment.These units provide isolation and1:1 conversion of standard currentsignals and are powered by theanalog input current signal loop.

    The DRSL-LPI series offers isolationbetween input and output, providessurge suppression and protectscontrol systems from transients andnoise. These units also eliminateground loops and can be used formeasuring floating signals. Lowpower consumption facilitates DINrail mounting without the need forany air gap. Measurement rangesare factory calibrated. These isolatorsoperates over a wide temperaturerange from -25 to 70°C (-13 to 158°F).
