Marine certification

Permanently measures and displays the network insulation resistance, capacitance and impedance

Description

Vigilohm IM20-H is an insulation monitoring device (IMD) permanently monitoring ungrounded/IT earthing systems as per IEC 60364-7-710 requirements. It monitors AC, DC and ACDC systems of short to medium length, with limited disturbance, up to 230V. IM20-H also monitors the IT transformer overload and overheating. IM20-H is versatile, adapting to networks resistance betwen 1000 and 10 MOhm with an accuracy <5% at 10 kOhm and 1 µF. To meet your applications, the device insulation alarm thresholds can be set between 50 and 500 kOhm. Once the alarm threshold is breached, it triggers an alarm that is relayed by 1 standard or fail-safe dry contact or by the HMI display. In addition, this alarm is relayed to the hospital remote display (HRP or LRDH) to alert the medical staff. It contributes to minimizing patient safety risks, downtimes, installations damages and operational losses. This IMDH is dedicated to healthcare installations where continuity of power supply is critical and where unexpected interruptions must be kept to a minimum. The device can be supplied by a 110VAC to 230VAC or a 125VDC to 250VDC source, with 15% tolerance, plus or minus. The device self-tests automatically to ensure that the monitoring of the ungrounded system remains permanent. It has been designed according to EN/IEC 61557-8 Annex A: Medical insulation monitoring devices (MED-ID) and also has Marine certification. The installation can be DIN rail or flush-mounted to meet your installation and the wiring is facilitated by removable terminals. The HMI design makes it easy for the user to do device configurations, manual test, or to get informed about the device and network status. Preventive maintenance can be planned to avoid interruptions thanks to preventive alarm and historical event logs of insulation resistance evolutions. Its native Modbus RS485 enables a complete reporting of product data to a supervision system such as PME for a centralized management. Vigilohm benefits from over 50 years' experience of insulation monitoring devices design by Schneider Electric. It is installed all over the world in the healthcare industry especially in Group 2 medical locations.
