Hi Everybody!

I have a 3 wires analog sensor output 4-20mA, its parametter is as attached file. I want to connect it to 6ES7 134-4MB02-0AB0 module. Could you please help me how to connect it!

Thanks.

Hello MrBin,

You should connect your 3-wire analog sensor like a 4-wire analog sensor.
This is a example for channel 1

Sensor Exitation+ (Supply) - ET200 Pin 3 (L+)
Sensor GND (Supply) - ET200 Pin 4 (L-)
Sensor Signal+ - ET200 Pin 1 (M0+)

Then should you connect ET200 Pin 2 (M0-) to ET200 Pin 4(L-).

Hope this is helpful.

Hello CaOd,

Thank about your help!

Can I connect as following:

Sensor Exitation+   -> 24VDC

Sensor Signal+       -> ET200 Pin 3 (L+)

Sensor GND           -> ET200 Pin 1 (M0+)

Then connect ET200 Pin 2 (M0-) to ET200 Pin 4(L-)?

Hello MrBin,

you're rigth, connect the ET200 Pin 2 (M0-) to ET200 Pin 4(L-).

Hello CaOd,

So, two ways which were mentioned above were right?

Thanks!
