The ISOMETER® IR425-D4 Insulation monitoring device for AC and DC IT systems:
Application control circuits
According to IEC 61557-8
Two separately configurable response values
Multi-functional LC display
The ISOMETER® of the IR425 series is designed to monitor the insulation resistance of unearthed AC/DC control circuits (IT systems) 0…300 V. DC components existing in AC/DC systems do not influence the operating characteristics. An external supply voltage allows de-energized systems to be monitored too.
