IM-ENG-116/GB 3. F UNCTIONAL ESCRIPTION 3.1 Overview The Mux2700 HART Signal Multiplexer (HSM) provides 32 signal channels for connection to field located, “smart” transmitters or control devices supporting digital communication according to the HART standard. The Mux2700 acts as a gateway between a Maintenance Workstation (MW) – typically a PC with suitable SW – and the field instrumentation. - Page 6 ZONE 1 FARM PCU # 2 II C BOILER MUX 2700 • Hazardous Non Hazardous Locations of Smart Instruments • Local or Remote Instruments Maintenance • Suitable for Existing Smart Field Device Transmitter, Valves, Mas Flow • Multiple • Independent to DCS System •...

Page 8: Application Guidelines
The Mux2700 HSM is not normally intended to be designed by the user in a specific application, but to be used as part of the Elcon HART Interface Solutions (H.I.S.) offering, which provides appropriate interconnection packages for a wide range of applications, as well as a set of compatible Maintenance Workstation solutions. This makes the Mux2700 application straightforward, because most “tricky”... -
Page 9: Software Architecture
I fact, the Mux2700 architecture is such that any internal single fault never result in any interference with an input connected 4/20 mA loop. For this reason, the MUX 2700 can be used as a monitoring device within safety-sensitive applications. -

Page 20: Connections And Mounting
IM-ENG-116/GB 7.3 Connections and mounting The Mux2700 HSM module is a plug-in unit intended for insertion in a suitable H.I.S. Termination Board. Therefore, the primary electrical connections (supply, field connection, serial lines) are made at the Termination Board level. Please refer to the relevant board instruction manual for details. The Mux2700 box –... - Page 21 IM-ENG-116/GB Warning ! Please remember that – unless the GND signals at both ends are connected to earth – the RS-485 communication line needs three wires (differential pair plus GND). It is not recommended to use the cable shield as GND connec- tion (i.e.

Page 22: Maintenance And Troubleshooting
No periodic maintenance or calibration is required for this product, which is also not intended for direct repair from the end-user. For these reasons, the Mux 2700 enclosure was not designed to be easily opened (and a special tool is in fact required at this purpose). -

12.1 Three-port isolation The three-port isolation structure of the MUX 2700 is depicted in Fig.8. As you can see, both the 24V supply input and the RS-485 serial interface are isolated from the HART section, that is to say, from the HART signals on the field devices. - Page 27 MUX terminal to whatever voltage level can be derived from a 24 Vdc supply, +20% tolerance included. The input-channels isolation specifications for the MUX 2700 are summarised in the following table: Channel number: 32 signal loops (64 terminals)
- Page 28 MUX is still fully functional. In a more formal term, the probability of any “electrical feedback” of the MUX 2700 on the loops signals is very low, and you can consider the control system for “fail-safe” applications (this doesn’t mean, however, that the MUX is fail-safe certified or that it will keep working properly when in a generic “single-fault”...
