Stefansvets Posts: 10 Rating: (0)	Hello! I have a little problem with analog output from AM2 A0, I want to be able to write 0-10 Volt to a damper actuator, to do that I also want to have a similar input, 0-10 Volt, that regulate the output amount. I am also wondering if there is a possability to have say 0-130 Ohm as output, regulated by 0-10Volt. Is this possible? Kind regards Stefan

Stefansvets Posts: 10 Rating: (0)	Ok, that is also one of the existing actuators, how do I get the output variation betveen 0-10 Volt from the LOGO! unit? I've been reading a lot on this forum and the tutorial in soft V8, but have not yet found any good explanation on this. Can I correlate this to a PT100 termo sensor? Thank you for your answer so far, this is really interesting and I'm still learning every day!! //Stefan

So you can adjust between 0.00 V and 10.00 V. If you want to evaluate a PT100 / 1000 with the logo, you will need an analog input module AM2 RTD.

Stefansvets Posts: 10 Rating: (0)	I have the analog input module for Pt100/1000, but I haven't figured out how to make the circuit diagram to control the analog output with auto regulation from temp.sensors or via up/down arrows on the TDE display. I guess i can figure out how to manage the buttons, but the sensor regulation is yet to come... //Stefan
