The fine small series electric valve actuator module is designed with a servo system (no additional servo amplifier is required), it only needs to be connected to DC4～20mA (or DC1～5V) signal and AC220V single-phase power supply to work. Built-in boundary terminal, wiring is extremely simple and convenient. The key component of the actuator module-the controller, adopts the most advanced hybrid integrated circuit, which is sealed and molded with resin, which is box-shaped, small in size and high in reliability. The feedback detection of the driving quantity adopts a high-performance conductive plastic potentiometer with a resolution of <0.4﹪with a self-diagnostic function. When a fault occurs, the indicator light on the controller will immediately send an indication signal. When the state selector switch for electrical equipment can set the off signal, the spool is in the fully open, fully closed or self-locking state.
