DESCRIPTION
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 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. This model is suitable for interfacing AI cards of safety PLCs with typical input impedance of 250 Ω and AO cards. The single TBE-D5001-HRT-004 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® 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-004 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.
