SJMC- M3 series angle stroke intelligent type

Introduction to the main features of the M3 series: 

1.Non-invasive (no need open the cover to set parameters);

2. LCD display with Chinese or English interface; 

3. On-site buttons with dust-proof protection design and non-through magnetic steel control the Hall element inside the electrical shell, allowing flexible parameter setting; 

4. Infrared remote control function, with the same operation setting method as on-site;

 5. need for batteries, with automatic memory function in case of power failure, ensuring the storage of set parameters and real-time display data; 

6. Photoelectric isolation of input output, with high voltage protection function, allowing free connection of any equipment and instruments;

 7. Using up to four single-chip computers for data exchange and processing to the module's response speed, thus achieving high-precision servo control; 

8. With perfect automatic phase identification, phase change, phase loss, overheat, overload and protection functions, ensuring that the electric actuator is intact under any fault condition;

 9. Phase change delay: When the actuator needs to change direction during operation, is an optimal delay time to protect the actuator from mechanical damage in sudden phase change; 

10. With positive and negative action selection function to meet the actual working; 

11. With the function of accumulating the number of times the electric actuator has been running, allowing users to always understand the total number of times the actuator has been working; 

12. Using spark-free phase change technology, thyristor components control the output, truly achieving modular control of large-power motors and product reliability; 

13. ESD emergency event function selection: emergency action original position, full open, full close; 

14. Comprehensive fault alarm (power failure motor overheat, phase loss, overload, signal loss, ESD beyond protection);

 15. Remote switch quantity control has two types: internal power supply and external supply, external power supply mode: DC24V, AC220V; 

16. The regulating type series electric actuator can be converted arbitrarily with switch type series electric actuator;

 17. This series of intelligent electric actuators have: local operation, on-site operation, infrared remote control operation, remote analog input control, remote switch quantity input control 

18. With the function of adjusting the sensitivity of the electric actuator, and setting the control range according to different needs; 

19. Mechanical torque measuring device: The use of mechanical transmission device to measure the load torque of the actuator is the method adopted by most traditional actu, its characteristics are high measurement accuracy, stable and reliable, our company's intelligent electric actuator still uses this method, and the precise value of the torque is transmitted the CPU for processing, to achieve high-precision torque parameter acquisition. 

20. Sensor fault protection: position sensor itself fault or actuator operation when the signal remains for 5 seconds and the switch signal is opposite, etc., at this time the travel monitoring system sends instructions, forcing the electric actuator to stop, and send and on-site alarm.

 21. Travel limit protection function: In the valve opening, valve closing travel setting and valve opening, valve closing operation, the servo module the travel signal acquisition unit, such as the electric beyond the protection range, at this time the travel monitoring system sends instructions, forcing the electric actuator to stop, send remote and on-site alarm.
