Product Specifications

ITEC Earth Fault Monitoring is a module for the monitoring of 24 volts power supply cables for remote system components (eg callstations). IT measures the resistance of both lines compared with the protective conductor (PE).

In accordance with the relevant standards a ground fault error is detected when a resistance of <50 kOhm against protective conductor is measured. A fault message is performed by relay contact and is indicated on the board by a LED.


  • Open Frame module for the installation in a system cabinet.
  • Easy installation, prepared for DIN-rail 35 mm.
  • All connections on plug terminal blocks.
  • Collective fault at relay changeover contact (Fault / OK).
  • Switch to lower sensitivity (10k) by jumper setting.
