EARTH FAULT MONITORING

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
