Good morning,

  I have this analog card with 4 channel, I use U0 and U1 for 0-10V analog inputs and I want to connect one sensor 4-20mA at I2 channel. 

  The sensor can connect 2wire or 3wire, it has L+, Analog out and L-. I want to connect it 3wire, 

L+ -> +24V power Supply

L- -> -24V power supply

AnOut -> I2+ Analog card

and not working, also i tried to put +24V to UV2 and also not working. 

I'm tried 2 wire:

L+ -> UV2

AnOut -> I2+

not working

Also when i put  U2- -> -24v power supply i had something like noise from U0+ channel, U0+ channel working from 0-27944 in PLC, when put U2- -> -24V power supply, change Channel 3 (I2+) when change channel 1 (U0+) from 0-1154... i don't know what it is... 

 Hello,

   Thanks for your response, my first step was to connect my sensor with 2 wire connection at UV2 and I2+ but my sensor didn't work  because UV2 didn't supply +24Vdc.

Hello,

Here is a link to manual:

SIMATIC ET 200SP analog input module AI 4xU/I 2-wire ST

See chapter 3 for wiring.

Channel 2:  Connect your sensor to Uv2 and I2+

Best regards,
