Electropneumatic Signal Converter is used for converting direct current signal into standard linear pneumatic signal for process control system applications. It is used for converting control signal 4-20 mA or 0-20 mA etc. coming from Electronic Controllers etc. into a linear 3-15 psi or 0.2-1 kg/cm² pneumatic signal for operation of control valves and dampers etc.
Please explain the working of it and if possible add a circuit diagram also.
Thank You.
Dear Anurag,
I suggest you a links and attached files in subject, good luck.

Hi Anurag Pandey,
Find these files for the examples of some EPC units.
Thankyou.

The concept of converting electric current into force and then pressure is by means of the electromagnetic.It is so one can make a DC magnet by flowing the current into a an electric coil. Then this magnet is made to move a piece of iron . The piece of the iron is connected to spring in one end while the spring is fixed in the other end. the piece of iron can be driven by the magnetic field of the electric current to actuate a plunger of a valve. The other method one can exploit the principle of the DC motor where one has a permanence magnet and then push the current in a coil in the magnetic field of the permanent, this coil is made to deflect against the restoring force of a spring. This deflection can be used to actuate a plunger.
Simply one exploits the electromagnetic effects to build current to force transducers for mechanical actuation.
Best wishes
