The Yokogawa VCLl-10-230 is an Electropneumatic Converter, also widely known as an I/P (Current-to-Pressure) Converter. Its core function is to translate a standard analog control signal (4-20 mA DC) from a controller into a precise proportional pneumatic output pressure. This allows electronic control systems to operate pneumatic actuators, control valves, and other pneumatically powered devices.
