The Hart Termination Board model TB-D5001-HRT-002 allows the remote monitoring of any HART-compatible 4/20 mA field loop. This is obtained by one locally mounted HART multiplexer module (MUX2700) and by terminal block interface connectors to access the relevant loops. The board is installed in series to the loop and is totally transparent to both transmitter and receiver. The Multiplexer plug-in module can manage up to 32 HART channels, with optional Hart multi-drop capability. Hot plug-in is fully supported: insertion and removal of a MUX unit can be done without switching off the power supply. The same is true as for the terminal blocks used to access the relevant Hart loops. The MUX unit connects, via the RS-485 interface, to an external PC running a suitable maintenance SW package. Each PC can communicate with multiple MUX units, located on different boards, in a multi-drop RS-485 mode.
