Hi,

I have a lot of manual on/off pneumatic valves in an oil line. I need to control these valves by a PLC. I wish to know if there is some manufacturer of electrovalves and inductive sensors with an interface for Fieldbus Foundation. The idea is to control and monitor the state of valve by a network FF. The electrovalves control the air supply for the principal valve.

Thanks for your help.

 

You have several options to monitor (or activate) on/off valves using FF.

Speak to your PlantWeb consultant to apply it correctly.

P+F and others have similar units.

Another neat solution is this:

Actuator, I/P, and position feedback all integrated into a single unit.
