1756-IF16 Single Ended/Differential - PLCS.net

makoester1 · January 2nd, 2018, 03:09 PM

Hello,

I have a 1756-IF16 configured for single-ended current inputs. I plan to add (4) 4-wire density transmitters. The operating manual for the density transmitters indicates that the 4-20mA signal is galvanically isolated. Does anyone see a problem with utilizing a single ended configuration?

Should be no issue. Will the Supply to each transmitter come from the same Power Supply?

The transmitters will be powered from the same 120VAC source.
