I/P Converter Typical I/P Converter Pneumatic Actuator를 동작시키는 Air Pressure는 Pneumatic Process Controller에 의해 직접 공급되거나, Electrical Signal → Air Pressure Signal 로 바꿔주는 Signal Transducer 또는 Converter에 의해 공급된다. Control valve의 경우엔 I/P Converter라고 알려져 있는데 그 이유는 4~20 mA의 Electrical Signal 을 3~15 psi의 Air Pressure Signal로 바꿔주기 때문에 그렇게 부른다.
Electrical Current Signal Input을 받아서 그에 비례한 Air Pressure Signal을 Output으로 내보낸다. 대게 외부에 직접 노출되지 않도록 Heavy Cast-metal Housing이고 Electrical Conduit Fitting이 되어 있다.
