  • One 4 to 20 mA Input to Two 4 to 20 mA Outputs with Full Isolation
  • Zero and Span Adjustments for Each Output
  • Full 1200 V Input/Output/ Power Isolation
  • Input/Output Loop Status LEDs
  • Output Test Button for Each Channel
  • Built-In Loop Power Supplies for Sink/Source I/O
  • Split, Convert, Boost, and Rescale Process Signals
  • Split Process Signals for Control and Validation
  • Interface a Process Signal with Multiple Panel Meters, PLCs, Recorders, Data Acquisition, DCS, and SCADA Systems

  • The DRSP-I Series DC currentsignal splitters accept one 4 to20 mA current input and provide twooptically isolated 4 to 20 mA currentoutputs that are linearly related tothe 4 to 20 mA current input. Thisprovides an economical solutionwhen one signal must be sent to twodifferent devices.Typical applications includeisolation, output splitting, outputdevice separation and redundancy(i.e. to prevent failure of the entireloop if one device fails), or acombination of these.The input signal is filtered, amplified,split, and then passed through anopto-coupler to the output stages.Full 4-way isolation (input, output 1,output 2, power) make this moduleuseful for ground loop elimination,common mode signal rejection,andnoise pickup reduction.
