The new HART Multiplexer System by GM International offers the possibility to drastically reduce the number of multiplexer modules, while maintaining a very high ability to control up to 7936 channels.

Through the integration of multiplexing units in the Termination Board (TB-D5001-HRT), the GMI HART System needs only one Modem 5700 to control 256 channels, allowing to manage up to 7936 channels utilizing only 31 modules.

Compared to the current state-of-the-art HART solutions available on the market today, which require 496 modules, the HART Multiplexer System by GM International drastically reduces the number of required multiplexer modules by 465, and subsequently saving cost.

The communication speed towards the system has also been greatly improved, reaching 115,200 bps, compared to the standard 38,400 bps of other systems on the market.

The new HART Multiplexer System represents a real and smart innovation, and brings with it many other advantages. In addition to ensuring the best performance of the system, it can also significantly reduce cost due to fewer components, cables, and spare parts, resulting in reduced need for storage.

As with almost all systems and components by GM International, the HART System is certified for SIL 3 applications, in compliance with IEC 61508 and IEC 61511.
