Electro-Pneumatic Transducer Bridges Gap From Electric to Air Signals

electropneumatic current to air voltage to air transducer for process control signals
In this age of electronics, pneumatics are still widely employed in process control, and the benefit of using compressed air to deliver control signals is not likely to diminish. Providing a bridge between electrical signals from controllers and pneumatic signals required at the input of operating devices is the function of an electro-pneumatic transducer.

The transducers come in many different versions to accommodate a wide range of possible input signals and two output pressure ranges. The compact units can be mounted in several ways, and NEMA 4X enclosures are available for installation outdoors or in washdown areas.

Some common applications where electrical control signals will be converted to pneumatic for device control.

  • Valve actuators
  • Pneumatic valve positioners
  • Damper and louver actuators
  • Final control elements
  • Relays
  • Air cylinders
  • Web tensioners
  • Clutches and brakes
