Impact on the I/O for a Re-located Instrument
Can you guys please advise me what will be the impact on the I/O for a re-located instrument.

I am currently working on revamping an ammonia plant. I am an instrumentation engineer. Can you guys please advise me what will be the impact on the I/O for a re-located instrument. Say if a Pressure transmitter is re-located? do i have to consider a New "Analog input" I/O.

please advise.

I wouldn't think so unless the run your adding is really far away, or your I/O is sensitive to signals picked up from other cables alongside yours in the run. Post more details someone will chime in.
