IMDIM15H Schneider Electric - Vigilohm - Permanent insulation monitoring - non-communicating - health application

IMDIM15H Schneider Electric - This insulation monitoring belongs to the Vigilohm range intended to monitor ungrounded electrical networks/IT, in accordance with installation and product standards.,According to IEC standards, it is mandatory to equip IT medical premises of Insulation Monitoring Devices (ISD).,This device is dedicated to monitoring AC, DC and ACDC medical computer systems.,It measures the insulation resistance of the system by injecting a low frequency alternating current between the network and earth.,The configuration will be defined in accordance with medical standards, on the front of the device, via the HMI screen.,The settings are linked to the insulation alarm thresholds of 50 to 500 kilohms and to the insulation alarms. overheating and overloading of the transformer.,It monitors networks up to 230VAC, 230VDC, in medical IT architecture, as well as medical IT transformer.,The black and white screen can display an insulation resistance of 100 ohms at 10 megohms.,The test starts automatically every 5 hours and on demand.,If a fault occurs, the system insulation resistance drops below the set threshold. An alarm is triggered via the IMD output relay within 4 seconds.,Without fault, the alarm turns off, the alarm relay returns to normal.,The device can be powered by a 110VAC to 230VAC source or from 125VDC to 250VDC, with a tolerance of plus or minus 15%.,This product can be installed on a DIN rail or recessed.,Its protection rating at the front is IP52, at the rear IP20. The overvoltage category is III.,The monitoring device is equipped with an RS485 communication port, Modbus protocol.
