We offer a wide range of HIG accessories as MDS-D remote monitoring module including the display from the ISOLGUARD range equipped with a touchscreen display showing the status or MDS remote signalling module designed for checking the status of the monitored IT network in a distant place from the HIG detector.
MDS-D/S -accesories of insulation monitoring device
The remote monitoring module including the display (MDS-D) from the ISOLGUARD range is a device equipped with a touchscreen display showing the status of isolated ungrounded IT power supply systems, monitored by insulation monitoring device HIG9x / 485 from the HAKEL production. Communication with the insulation monitoring devices takes place via RS485 using the internal protocol. The MDS-D panel further includes a second line RS485 (external busbar), which transfers the collected data to the user master system. The communication on this route takes place via telegrams, based on the PROFIBUS protocol.

MDS 10T Tango -accesories of insulation monitoring device
MDS remote signalling module is designed for checking the status of the monitored ungrounded IT power supply system in a distant place from the HIG insulation monitoring device. On insulation monitoring device HIG91/92/95 it is possible to connect 5 MDS 10T. Interconnection HIG9x+TOM→MDS 10T is performed 5–by conductors. Under normal conditions, on the front panel of the MDS 10T only a green signal lamp OPERATION shines. In the case of failure evaluated by the HIG sensor, on the module MDS 10T, red FAILURE signal lamp starts to shine (RCRIT) and, at the same time, the piezo-siren is activated. The operator of the health or supervising workplace has the option to disconnect the acoustic warning by pressing the STOP ALARM button. In the case of error due to overheating or current overloading of the health transformer, on the MDS 10T module, a yellow FAULT signal lamp starts to flash and the piezo siren is activated. In this case, the operator does not have the option to disconnect the acoustic warning because it concerns the fatal status of the monitored ungrounded IT power supply system which must be resolved by qualified technical staff.
MDS 10T MPS – accesories of insulation monitoring device
Module for remote signalling MDS10T or set MDS10T+MPS (MPS… module for auxiliary signalling) are designed for inspection of the status of the monitored ungrounded IT power supply system in a distant place of the HIG insulation monitoring device. It is possible to connect 5 pcs MDS10T or 2 pcs sets MDS10T+MPS to one HIG91/92/95. Interconnection HIG+TOMMDS10T (+MPS) is performed by 5 conductors. Under normal conditions, on the front MDS10T panel, only a green READY/OPERATION signal lamp shines. In the case of the failure of the insulating status evaluated by the HIG insulation monitoring device on the module MDS10T red FAULT signal lamp starts to flash (RCRIT). The built-in siren is activated and light signalling is activated MPS module. The operation of the health or supervising workplace has the option of acoustic warning and flashing of the module disconnect by pressing the STOP ALARM button. In the case that due to the overheating or current overloading of the health transformer, on the MDS10T module a yellow signal lamp starts to flash FAILURE. At the same time, the built in siren is activated and lighting signalling the MPS module is activated. The health operators or supervising workplace has the option to disconnect the acoustic warning and flashing of the MPs module by the STOP ALARM buttons.
TL* serves for the adaption of HIG circuits to 3-phase ungrounded IT power supply system 3 x 400 V AC (or 500 ev. 600 V AC). Commonly, these 3-phase inductors are produced on the basis of special requirement.
TAR 1D – accesories of insulation monitoring device
Current transformers TAR are designed for reading the values of off-taken current from the health transformer. In the standard version it is provided in the ratio 100 A / 5 A / 3 VA / 1 % in the ring-type version with a cable. The current transformers with another ratio than 100 A / 5 A are supplied by the company on the basis of the request of the client.
