Dieses Gerät gehört zur Vigilohm Reihe, die für die Überwachung von ungeerdeten Energieversorgungen (IT-Systeme) gemäß den Installations- und Produktnormen entwickelt wurde. Diese Isolationsfehlerortung ist nur möglich, wenn sie mit der IM400-Serie, XM300 oder XM200 verbunden ist. Dieses Gerät dient zur Überwachung von 12 Einspeisungen, AC, DC und ACDC, bis zur Toroidgrenze von 1000 V. Die Konfiguration erfolgt über den HMI-Bildschirm an der Vorderseite des Geräts. Die Einstellungen beziehen sich auf Alarmschwellenwerte. Es zeigt an, welcher Feeder einen Isolationsfehler hat. Autotest startet automatisch alle 5 Stunden und bei Bedarf. Falls der Isolationswiderstand unter den eingestellten Schwellenwert fällt, wird über das IFL-Ausgangsrelais und die HMI ein Alarm ausgelöst. Sobald kein Fehler mehr überwacht wird, wird der Alarm gelöscht und das Alarmrelais kehrt in den Normalzustand zurück. Das Gerät kann mit einer Spannung von 24 VDC bis 48 VDC mit einer Toleranz von plus oder minus 15 % versorgt werden.
