Hi, 

How can we connect 2 wire transmitter into expansion module AM2? 

Thank you in advance. 

Hi, 

We have 2 wire transmitter 4-20 mA "Pressure transmitter", we need to connect it to Logo expansion module. 

How? 

Hi, 

Why do you add a voltage source 24V? 

The voltage source must be 24V DC or may be 12V  DC or 220V Ac

Hi, 

you add voltage source in your previous comment

 Can you help me and give me the  answers? 

Because Iam sad due to Corona virus in our country. 

Maybe there is a misunderstanding, because a question mark is absence at the right position.

First, corona virus is a problem on the whole world.

For an expansion module AM2 you need a supply of DC24V, not DC12V or AC230V. For the sensor you also need a supply, mostly DC24V is possible, see instructions of your sensor. The connections are explained clearly by ixo65.
