Schneider Electric IMDIFL12 IMDIFL12 Isolation monitor No. of relay outputs: 1

This device belongs to the Vigilohm series, which was developed for the monitoring of ungrounded power supplies (IT systems) according to the installation and product standards. This isolation troubleshooting is only possible when connected to the IM400 series, XM300, or XM200. This device is designed for monitoring 12 AC, DC and ACDC outputs up to ring core voltage of 1000 V. The configuration is set from the front of the device via the HMI screen. The settings refer to the alarm thresholds. It indicates which outlet has an isolation error. Autotest starts automatically every 5 hours and if necessary. If the insulation resistance falls below the set threshold value, an alarm is triggered via the IFL output relay and the HMI. As soon as no more faults are detected, the alarm is cleared and the alarm relay returns to its normal state. The device can be supplied from a 110VAC to 440VAC source or from a 110VDC to 440VDC source, all with a tolerance of plus or minus 15%.
