DIN RAIL ISOLATED BARRIERS

DIN rail isolated barriers, also referred to as transformer isolated or galvanically isolated barriers, are safety barriers with additional electronics to isolate and condition the signals.

Adding the isolation offers the main advantage of not requiring IS ground connections.

The signal conditioning of isolated barriers simplifies the selection process as each isolated barrier is manufactured for specific functions such as switching, temperature measurements or 4-20mA readings.

Advantages:
  • does not require IS ground
  • integrated signal conditioning.

    Other considerations:
  • larger power requirements
  • higher cost than grounded barriers
