The HART® Termination Board model TB-D5001-HRT-004 allows the remote monitoring of any HART®-compatible 4/20 mA field loop. It is suitable for interfacing AI cards of safety PLCs with typical input impedance of 250 Ω and AO cards. This is obtained by one locally mounted HART® Multiplexer Modem 5700 and by terminal block interface connectors to access the relevant loops. The board is installed in series to the loops and is totally transparent to both transmitter and receiver. The single TB-D5001-HRT-004 Termination Board supports 32 channels. Yet, it can be extended with additional TB-D5001-HRT-004 units (up to 8) to manage all 256 channels available on the HART® Multiplexer Modem 5700. 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 TB-D5001-HRT-004 is SIL 3 certified as non-interfering with the signal loops.
