| DKJ-610EX flameproof electric actuator DKJ, DKZ series electric actuator is a terminal control device for industrial process measurement and control system, it can be converted into a control signal system of angular displacement and linear displacement of the output shaft, position control valve closure member or other regulatory agencies, the controlled medium according to the specified state working system. The electric actuator is divided into proportion and integral type according to the control mode. The proportional actuator is made up of an electric servo amplifier and an integral actuator. It can compare the control signal of the system with the feedback signal on the output shaft position (closed loop control) to change the output shaft's stroke and make it proportional to the output signal. The integral actuator is made up of servo motor, reducer and position transmitter. It can cooperate with electric operator to realize remote operation of valve or other regulating mechanism. Main technical parameters DKJ and DKZ series electric actuators are manufactured according to the regulations of People's Republic of China national standard GB11922-89 "electric actuators for industrial process measurement and control systems". 1. input signal: electronic 420mA: DC or DC 010mA, common type: switch 2. input channel resistance: 250 ohms or 200 ohms The number of 3. input channels: 3 common type amplifier and 1 electronic type 4. basic error: 2.5% 5. difference: less than 1.5% 6. dead: less than 3% 7. damping characteristics: less than or equal to 3 times the half cycle 8. power supply voltage: 220V or 380V, 50Hz 9. working environment: temperature: -10 0 C 0 C+55, humidity: less than or equal to 95%, the surrounding air does not contain corrosive nature |
