Insulation monitoring device HIG24VDC, HIG48VDC and HIG110VDC for shipbuilding applications

The insulation monitoring devices ISOLGUARD HIG24VDC/48VDC/110VDC produced by HAKEL are designed for monitoring the insulation status of direct current IT power supply systems. The device continuously monitors the insulation state of the positive and negative output of an insulation power supply system against the base point. For stationary devices it is usually PE conductor. The potential free switching contact of the signalization relay FAULT will switch during the insulation resistance decrease of + or – output. A fault is also indicated by LEDs on the front panel.

The insulation monitoring device is equipped to display the numeric values of the measured insulation resistance. The measured resistance value of the positive and negative output of a controlled network is displayed on the device´s screen. There are buttons for setting the parameters of the insulation monitoring device and signalling LEDs to display the status of the controlled network and the device itself.

It is possible to connect the insulation monitoring device to the panel MDS-D equipped with a touchscreen by means of the RS485 busbar. The MDS-D panel displays the actual measured values and the actual insulation monitoring device setting.

HIG24VDC/48VDC/110VDC can communicate with the master computer through an industrial RS485 bus-bar with the protokol derived from the PROFIBUS protocol.

Only one insulation monitoring device can be connected to the same ungrounded IT power supply system.
