The HART® Termination Board model TB-D5001-HRT-003 allows the remote monitoring of any HART®-compatible 4/20 mA field loop. This is obtained by one locally mounted HART® Multiplexer Modem 5700 series and by interface connectors to access the relevant loops. The single TB-D5001-HRT-003 Termination Board supports 64 channels. Yet, it could be extended with additional TB-D5001-HRT-003 units (up to 4) to manage all 256 channels available on the HART® Multiplexer Modem 5700 series. The Mux unit connects, via the RS-485 interface, to an external PC running an FDTbased software package (PACTware™, etc...) through a dedicated Device Type Manager (DTM). The PC can communicate with multiple Mux units, located on different boards, in a multi-drop RS-485 mode. The HART® Termination Board TB-D5001-HRT-003 is SIL 3 certified as non-interfering with the signal loops.
