Schneider Electric IMDIFL12L IMDIFL12L Monitoring relay 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 error detection is only possible if it is connected to the IM400 series, XM300 or XM200. This device is used for monitoring 12 power supplies, AC, DC and ACDC, up to the limit of 1000 V. Configuration is performed via the HMI screen on the front of the device. The settings refer to alarm thresholds. It indicates which feeder has an isolation error. Autotest starts automatically every 5 hours and if necessary. If the insulation resistance falls below the set threshold, an alarm is triggered via the IFL output relay and the HMI. As soon as no fault is monitored, the alarm is cleared and the alarm relay returns to its normal state. The device can be supplied with a voltage from 24 VDC to 48 VDC with a tolerance of plus or minus 15 %.
