This Termination Board with Enclosure (TBE) provides direct connection between the I/O Card of the system and 2-wire passive or active transmitters. At the same time, it makes available an interface for the remote monitoring of any HART®-compatible 4/20 mA field device. This is obtained by a locally mounted HART® Multiplexer Modem 5700 series and by terminal block connectors to access the loops. The single TBE-D5001-TRI-001 Termination Board supports 32 channels. Yet, it could be extended with additional units (up to 8) to manage all 256 channels available on the HART® 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 24 Vdc Power Supply of the TBE is connected to two plug-in terminal blocks, for a redundant power supply.
