      Description

      Designed to provide a convenient way of powering and isolating process signal inputs. Convert and isolate three or four wire transmitters to isolated two wire signals.
      Protect the input cards of PLCs while at the same time providing power to the loop providing a high level of system security by isolating and powering each input separately.
      In contrast to single power supply systems, should one transmitter short the 24 VDC supply, only one measurement is lost and not all of those powered from a common 24 VDC supply.

      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.
      • Process signal amplification in situations where the line impedance is too great to effectively drive the required instrumentation.
      • Individual channel isolation and the elimination of common mode offsets.
