RC Compensator Wiring Termination

Hi All,

I have problem with RC Compensator wiring termination, how to design of simplex or redundand system on RC Compensator wiring?

Actually till now the system of End of Line still not working if the polarity (+) to Terminal "R" dan polarity (-) to "-" of RC Compensator if the Module SLS redundant or simplex card the polarity (+) to Terminal "S" dan polarity (-) to "-"

Thanks and Best Regard,

    Hi Syallim,
    I think you are referring to the Terminated end of the SISNet Local peer bus. That is likely an RC circuit to reduce noise. The local peer bus is terminated by 120 ohm BNC terminators on the right one-wide carrier connected to the last 8-wide carrier. There are two of them.
    If this is what you are looking at there is a helpful document, : "Installing Your DeltaV SISTm Process Safety System Hardware" D800025X092 May 2015 available through your Guardian website under Support>Resources>DeltaV SIS the hyperlink reads "DeltaV SIS Installation Guide, May 2015".

    In reply to Sal Salamone:

    I mean about "The DeltaV SISTm Conditioning Components", not BNC Terminal
    The Wiring Connection for "End of Line" not issue, but the problem are "RC Compensator" still not working till now.
    I am confuse with the wiring termination RC Compensator, can you info the wiring termination of RC Compensator

    Refer to white paper : DeltaV SIS Process Safety System, Product Data Sheet December 2017
