Answer Posted / abhinendra singh bhadauriya
i/p is a converter that converts 4-20 ma input signal to an
pneumatic signal(3-15 psig or 6-30 psig).i/p converter took
the input in the form of current (ma)and produce an output
in the form of pneumatic signal (air)which is used to
maitain the position of control valve.
but e/p positioner is an device which also reside i/p
converter inside it along with the positioner , means e/p
positioner is the combination of i/p converter and
positioner which receive the electric signal (as current or
voltage)and convert it in pneumatic form which is
responsible for the operation of control valve.
