  •  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. 

    Insulation monitoring for AC/DC control circuits 0…300 V
    Two separately adjustable response values
    Preset function (automatic setting of basic parameters)
    Connection monitoring system/earth
    LEDs: Power On, Alarm 1, Alarm 2
    Internal/external test/reset button
    Two separate alarm relays (one changeover contact each)
    N/O or N/C operation, selectable
    Fault memory behaviour, selectable
    Self monitoring with automatic alarm
    Multi-functional LC display
    Adjustable response delay
    Two-module enclosure (36 mm) 

    AC/DC control circuits in the industrial sector, mechanical engineering, power plants, elevators, automation systems etc.
    AC/DC control and auxiliary circuits in accordance with DIN EN 60204-1 “Electrical equipment of machines”, IEC 60204-1, EN 60204-1
    AC/DC auxiliary circuits in accordance with DIN VDE 0100-725 (VDE 0100-725)
    Smaller AC/DC IT systems such as lighting systems
