とを特徴とする電空変換器。 In an electro-pneumatic converter for controlling pneumatic output in accordance with input current, the input processing means generates a signal voltage corresponding to the input current and also generates a circuit power supply, and a digital converter converts the signal voltage into a digital signal. a conversion means, a pressure/frequency conversion means for converting the pneumatic output into a frequency output, a displacement/frequency conversion means for converting a stem displacement linked to a valve of a pilot relay that outputs the pneumatic pressure output into a frequency signal, A feedback signal corresponding to the output and the frequency signal is input, and based on this frequency output, the gain of the output signal with respect to the frequency signal is calculated, and the deviation between these and the digital signal is calculated, and an output signal corresponding to this deviation is obtained. An electro-pneumatic converter comprising: a microcomputer that outputs an output to actuator means for controlling the pilot relay.
