ISOMETER® IR425-D4

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.

Caratteristiche

  • 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)
  • Push-wire terminal (two terminals per connection)

Applicazioni

  • 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
