TB-D5001-HRT-005
SIL 3 HART® Multiplexer Termination Board 1 position for up to 32 channels (extendable to 256 chs) with 1/5 V conversion resistanc
Description
The HART® Termination Board model TB-D5001-HRT-005 allows the remote monitoring of any HART®-compatible 4/20 mA field loop, while converting the input current into a 1- 5 V signals. 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. The single TB-D5001-HRT-005 Termination Board supports 32 channels. Yet, it can be extended with additional TB-D5001-HRT-005 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-005 is SIL 3 certified as non-interfering with the signal loops.
