Analog module 1746 IF4 AB

okay! my issue is with the wiring !!

could you explain me a bit more why the vendor puts 4-20mA in the brown and that cable you have to connect it to the power source and not to the input module ??

An the other cable (blue ) that says 0-30Vdc which I would put to the power supply, it goes to the module ??

thanks!

Can you provide us with the complete catalog number of the level transmitter?

Or a link to the manual.

Maybe this will help.

FYI. the article uses current flow vs electron flow.Please don't let that confused this issue. See link

So basically you are saying that I dont have to guide to the "letters" of the label , i mean ( 4-20ma and 0-30 V) but yes to the polarity ( brwn + and blk - ) ¿?¿?

 

[Mickey]

but yes to the polarity

Yes.

Loop powered transmitters require a min voltage to operate, you would have to look at the specs. A 24vdc power supply should be more then enough.The min. is usually lower then that, the specs should tell you that.
30vdc may be the max.
