June 7, 2017 - The HART Multiplexer System by GM International is designed to offer the possibility to reduce the number of multiplexer modules, while maintaining 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 HART solutions available on the market today, which require 496 modules, the HART Multiplexer System by GM International reduces the number of required multiplexer modules by 465. The communication speed towards the system has also been improved, reaching 115,200 bps.
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.
