The 381 adjustment-type quarter-turn electric actuators produced by Tianjin Majyofu mainly include 381 ordinary adjustment-type quarter-turn electric actuators and 381 explosion-proof adjustment-type quarter-turn electric actuators . 381 Adjustable quarter-turn electric actuator is AC220 single-phase AC power supply, accept DC 4~20mA from DCS, PLC system and other operators, standard signal to control the actuator to open or close the valve or automatically adjust. The electronic control module uses the most advanced hybrid integrated circuit, contains complete protection functions, can be controlled on site or remotely, is designed in the form of a tweezers, and is sealed with a resin cast. 381 Adjustable Rotary Actuator Driven actuators adopt high-performance conductive plastic potentiometers, high precision, long life, etc., and can be combined with various angular travel adjustment mechanisms to form high-performance, high-reliability electric control valves. Therefore, it is widely used in metallurgy, power generation, petrochemical, papermaking, light industry and environmental protection industries. 381 Adjustable Rotary Actuator Main Features : 1, the design of the actuator servo (servo amplifiers need to reprovision), only the access DC4 ~ 20mA (or DC1 ~ 5V) signal and a single-phase power to AC220V work. Built-in terminals, the wiring is extremely simple and convenient. 2, the key member ─ actuator controller, using the most advanced hybrid integrated circuit, sealed with resin molding, pocket-like outer shape, small size and high reliability. 3 , 381 actuator drive feedback detection using high-performance conductive plastic potentiometer, resolution <0.4%. 4 , 381 actuator with self-diagnostic function, when a fault occurs, the indicator light on the controller will immediately send out an indication signal. 5, a state 381 to select the actuator switch can be set off signal (the valve body is fully open, fully closed or locked state). 6, the actuator 381 can be set to a state selection switch (positive and negative action). 7, the actuator switch can be set to a state selection input signal (DC4 ~ 20mA or DC1 ~ 5V). 8. It is easy for the implementing agencies to adjust the work zero (starting point) and travel (end point). 9, actuator when a sudden power failure, the valve can ensure self-locking. 10, synchronous belt drive actuator, effectively reducing the noise. 11 , the implementation of delay protection agencies , rated load, the state can implement the state of self-locking, when the fault occurs, can immediately start the protection, and reverse operation can be canceled delay protection. 2. The main technical parameters of 381 adjustable quarter-turn electric actuators : 1, power to the actuator AC220 ± 50%, 50HZ. 2, the actuator power consumption (rated load) A specification actuators 50VA; specifications B actuators 150VA; C specification actuators 220VA. 2.3 Input signal: DC 4 ~ 20mA or DC 1 ~ 5V. 4 , the actuator output signal: DC 4 ~ 20mA (load resistance less than 500Ω). 5 , 381 Actuator control accuracy of the basic error: ± 1% Return difference ≤ 1% Dead zone ≤ 1% 6, the actuator working stroke adjustment range: "Zero" ± 25% "stroke" 20% to 100% 7 , external wiring: input and output signals should be shielded cable. The power cable must not share a cable with the signal cable.
