Sensor 4-20mA

I need to install a pressure sensor -1 to 0 bar in the logo without a converter system

How can I do it? what parameters i need to use?

I need a scale to mbar

You can connect a 4-20mA sensor at a LOGO! AM2 module.

Assuming you want -1000 m bar for 4mA and 0 for 20mA you can scale it with:

Gain= 1.25

Offset= -1250

You can connect a 4-20mA sensor at a LOGO! AM2 module.

Assuming you want -1000 m bar for 4mA and 0 for 20mA you can scale it with:

Gain= 1.25

Offset= -1250

With scaling you can't get .0,001 bar ( = -1000 mbar), only - 0,01 bar. 

It works as I wrote; just try it.

Hint: Parameter “Decimal places in a message text” in our analog block is 0 for this application.

no I haven't. Maybe using de I7 and I8 input. Can I connect directly the sensor?
