Overview
The DKJ-210 angular stroke electric actuator is an execution unit in the DDZ-II and III series instruments, used in conjunction with the DDZ-II and III control unit instruments It is powered by an AC power source and receives a unified standard signal of 4-20mA, DC (or 0-10mA, DC). The input signal and feedback signal from the position transmitter are compared by a servo amplifier to output a switch signal, which drives the motor. After mechanical deceleration, the input signal is converted into the corresponding output shaft angular displacement:
Product Details
DKJ-210 angular stroke electric actuatorIt is an execution unit in the DDZ-II and III series instruments, used in conjunction with the DDZ-II and III control unit instruments It is powered by an AC power source and receives a unified standard signal of 4-20mA, DC (or 0-10mA, DC). The input signal and feedback signal from the position transmitter are compared by a servo amplifier to output a switch signal, which drives the motor. After mechanical deceleration, the input signal is converted into the corresponding output shaft angular displacement to automatically operate the air damper, butterfly valve, ball valve and other devices, completing the automatic adjustment task of the system. It is widely used in the adjustment systems of industrial sectors such as power plants, metallurgy, petroleum, chemical industry, machinery, light industry, textile, food and medicine
DKJ-210 angular stroke electric actuatorFunctional characteristics of DKJ-2100 electric actuator for wind turbine
The position transmitter adopts gear transmission to ensure reliable and accurate limit positioning
Using a precision conductive plastic potentiometer with angle indication for easy debugging and clarity
The circuit adopts a modular structure encapsulated with epoxy resin and undergoes high and low temperature aging to ensure stability and reliability
The motor adopts an outdoor servo motor with overload protection
