IR420-D4-1 - Digital Ground Fault Monitor / Ground Detector Ungrounded (Floating) AC Systems

Download the IR420-D4-1 datasheet PDF. This datasheet also covers the IR420-D4 variant, as both devices belong to the same digital ground fault monitor / ground detector ungrounded (floating) ac systems family and are provided as variant models within a single manufacturer datasheet.

Description

The A-ISOMETER® IR420-D4 monitors for ground faults in ungrounded AC systems from 0 to 300 V by measuring the system's insulation resistance.

The IR420-D4 is designed to provide predictive maintenence and detect ground faults in ungrounded systems before leakage current may even be present.

Features

  • Insulation monitoring for ungrounded, low-voltage circuits AC 0…300 V.
  • Two separately adjustable response values.
  •  Preset function (automatic assignment of basic parameters).
  • Connection monitoring.
  • LEDs: Power On, Alarm 1, Alarm 2.
  • Internal/external test/reset button.
  • Two separately adjustable SPDT contacts.
  • Normally energized or normally de-ener- gized operation.
  • Latching or non-latching behavior.
