• Insulation monitoring device for AC and DC IT systems
  • Application: control circuits
  • Two response values adjustable via rotary switch
  • Measured value display via LED band
  • Very compact - only 1TE width (18 mm)

The ISOMETER® is an insulation monitoring device according to IEC 61557-8 for IT systems. It monitors the insulation resistance of unearthed 3(N)AC, AC and DC main and control circuits (IT systems).

The DC components existing in AC/DC systems can have an influence on the response behaviour if an insulation fault occurs downstream of rectifiers with an electrolytic capacitor.

The separate supply voltage of the iso415R-24 also makes it possible to monitor a de-energised system.
