      Applications
      • Elimination of the effects of ground loops from distributed process signals.
      • The protection of signals against common mode interferences such as motors, contactors and power line surges.
      • The outputs can drive loads of up to 500 Ω which is sufficient to drive a measurement loop of several kilometres.
      • Individual channel isolation and the elimination of common mode offsets for non-isolated computer and PLC inputs.
