What are the advantages and disadvantages of connecting the Mux2700 in series and in parallel?
The parallel connection has the advantage that the mux panel can be removed, or added without disturbing the field wiring and DCS. This makes the parallel connection useful for retrofit applications. The disadvantages of the parallel connection are that the customer will have to usually add a second wire underneath the field wiring terminal blocks in order to make the connection to the mux panel, and they cannot use the integrated HART filter option on our panels as this can only be implemented using a series wiring technique. Series wiring has the advantages that the HART filters can be used, and there is only one wire per terminal block, which is usually more acceptable to the plant level personnel. The disadvantages of series wiring installations are that it is more difficult to install on retrofit applications, and the panels once installed cannot be removed without disrupting the system.
