Product information for ISOMETER® IR420

The ISOMETER® IR420 monitors the insulation resistance of unearthed AC control circuits (IT systems) 0…300 V. If the systems to be monitored include DC components, such as switched-mode power supplies or solenoid valves, the display and operating characteristics may be affected.
The display and response values apply to pure AC systems. An external supply voltage allows de-energised systems to be monitored too.

Characteristics of ISOMETER® IR420

  • Insulation monitoring for IT control circuits AC 0…300 V
  • Two separately adjustable response values
  • Preset function (automatic assignment 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 message
  • Multi-functional LC display
  • Adjustable response delay
  • Two-module enclosure (36 mm)
  • RoHS-compliant
  • Push-wire terminal (two terminals per connection)

Applications for ISOMETER® IR420

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