Control Belimo Damper Actuator with Arduino

Other Hardware General Electronics
1

I am looking to control a Belimo Actuator (LF24-SR(-S) US) using feedback from a pressure transducer.

I need to have an input signal into the Arduino from a pressure transducer (4-20mA) signal, then thru a control algorithm convert that input into a control signal for the actuator (0-10V or 4-20mA). Is this feasible for an Arduino? I will take any guidance!

Cut sheet for the Belimo actuator and the pressure transducer is attached.

Thanks!!

Google for "Arduino 20mA" to find appropriate I/O modules.

4 to 20ma is great over a long distance but the sensor and valve also have options for voltage control so you have a lot of options

So it is possible to receive that input signal from the pressure transducer and send a control signal to the actuator? I suppose 0-10V would work, but it sounds like I will need a filter of some kind either way to get a true analog signal?

get a mod to move this to the electrical component section the guys over there know the bets way to do it.

As for the arduino part thats not going to be a problem.
