Loop vs Self Powered Control Instrumentation

[@abumusa8989]

Very helpful. Could u Plz make a video on why 4-20mA is good rather than 0-20mA. What is fail safe property?

[@fernandolopez4729]

abu musa because you know 4 is zero and it’s working. 0 might be 0% or just not working. Wouldn’t know the difference.

Instrumentation noob here. If you have a loop powered field device (pneumatic valve positioner controller in this case) using 4-20 mA, but the AO cards you have are set up to send 4-20 mA for 3- or 4- wire devices, how could one make this work without replacing either the AO card or positioner?
