DKJ serial motor operator

DKJ rotary-motion electric actuator is the execution unit of DDZ-â…¡ & â…¢ serial instruments, applies with DDZ-â…¡ & â…¢ control unit instruments. It is driven by ac power supply, receives unified standard signals 4-20mA, dc (or 0-10mA, dc), input signal and feedback signals of position transmitter, output switch signals after compared with servo amplifier, drives motor, transfers input signal into corresponding displacement of twist angle of output shaft; operates shutoff damper, butterfly valve, and ball valve, etc and finishes the automatic regulation of system. It is widely used in regulation system of generating plant, metallurgy, petroleum, chemical, machinery, light industry, textile, food, and pharmacy industries, etc.Characteristics:
●Position transmitter adopts gear drive to ensure the reliable and accurate limit.
●Adopt precise conductive plastic potentiometer with angle indication, convenient and easy to understand.
●Circuit adopts modular structure sealed by epoxy resin after low-temperature aging process to ensure stability and reliability.

●Electric motor adopts outdoor servo motor with overload protection.
