DKJ intelligent rotary electric actuator Features

DKJ series of intelligent rotary actuator to AC power as the power to accept a unified standard signal 4mA ~ 20? MA, dc or digital signal, the output shaft is 0 ~ 90 ° angular displacement by manipulating throttle linkage tailgate, butterfly valves, and other regulatory agencies, the implementation of the process control system automatically adjusts the task. DKJ series of intelligent rotary electric actuators is the introduction of the British Roethke (ROTORK) Company advanced technology products, and the design and manufacture of new products combined with the actual use of domestic requirements. ? DKJ intelligent rotary electric actuator has the following features: ??? 1, actuator electronic control device built-integrated structure, without reprovision servo amplifier, can directly accept 4 ~ 20 mA analog signals or passive? switch signal. ?? ?? 2, the electric actuator mechanical gearbox worm gear structure with self-locking function. Housing made of aluminum alloy, light weight. ?? ?? 3, DKJ intelligent rotary electric actuators built three standard circuit board, display control panel main board with CPU that is, the electronic non-contact power driver board and with digital control and operation of the button, the circuit board is generic, maintenance and replacement is very convenient. ?? ?? 4, the actuator is equipped with a hand-held wireless remote control (optional component). Stroke actuator commissioning and parameter setting can be used both locally display the operation buttons on the control panel, you can use the remote control. ?? ?? 5, the actuator travel site commissioning as long as the closed position and an open position of choice to complete, debugging is very simple and does not require any additional debugging instruments and equipment. ?? ?? 6, DKJ intelligent type rotary electric actuator with precision conductive plastic potentiometer for position detection element, and individually sealed in a round box. ?? ?? 7, the bidirectional electric actuator torque protection. Torque adjustment mechanism and torque switching is individually sealed. ?? ?? 8, the actuator has an electrical braking function, without oscillation phenomenon, and no additional mechanical brake on the motor parts. 9, DKJ intelligent type rotary electric actuator having a shutdown input signal, breaking the feedback signal, such as two-way over torque fault diagnosis and fault protection, and with fault display and fault alarm signal output (switch contacts). ?? ?? 10, about the position of the electric actuator appliances, switch signal output midway open position and can set the time for the control system used. ?? ?? 11, DKJ intelligent rotary electric actuators regardless of whether the motor is charged, can be safely switched to manual mode, shake-place handwheel. http://www.mjfzk.com/
