Applications

The APCS SI239 Signal Isolator v2 is widely used for signal conversion with PLCs, loop prevention, and noise filtering:

  • High-voltage/high-current DC signal isolation up to 2000Vdc/10Adc
  • True RMS conversion of AC signals for accurate PLC input
  • Summing (adder) or differencing (subtractor) two process signals
  • Min/max selection between redundant sensor signals
  • Preventing ground and current loops in PLC interfacing
  • Protecting instrumentation from dangerous field voltages
  • Filtering common-mode noise on high-voltage signal circuits
  • Loop-powering isolated transmitters without external supplies
