Product Diagram The SI231 is an isolated loop-powered signal converter for common process signals, and features:

  • Field configurable inputs 4-20mA, 0-1mA, 0-10mA, 0-20mA, 0-1V, 0-2V, 0-5V, 1-5V & 0-10V.
  • 2-wire or 3-wire output loop power supplies.
  • 2000Vrms isolation.
  • Field configurable response time.
  • Front adjustments for span and zero.

Common applications include:

  • Signal conversion for input to PLC's.
  • Prevention of ground and current loops.
  • Protection from dangerous floating voltages.
  • Filter of common mode noise
