This Termination Board with Enclosure (TBE) 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 field smart devices. The single TBE-D5001-HRT-003 Termination Board supports 64 channels. Yet, it could be extended with additional 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 FDT-based 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 TBE-D5001-HRT-003 is SIL 3 certified as non-interfering with the signal loops. The 24 Vdc Power Supply of the TBE is connected to two plug-in terminal blocks, for a redundant power supply.
