Insulation monitoring Relais

The working principle of the isolation monitor for IT systems in medical use rooms, as well as hospital and ambulatory clinic, is based on applying a dc voltage or a codified signal, between the secondary of the isolation transformer and the equipotential node of the installation . Borna niroo karan company(Bornika) is the exclusive representative of Contrel on buying , selling, consulting services for automation systems and protective relays including Insulation monitoring Relais.


Insulation Relay HRI-R40

Model: HRI Order code: HRI-R40 , HRI-R40w

Insulation Relay HRI-R40 insulation's resistance monitoring is carried out applying a measure's signalling between isolated network and earth . reducing problems caused by the presence of direct-current components on network (rectifiers).
