SJMC- M8 series multi-rotating intelligent type

Introduction to the main features of the M8 series: 

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

2. LCD display with Chinese or English interface; 

3. The on-site knob adopts a dust-proof protection design and a non-through steel control of the Hall element inside the electrical shell, which allows flexible parameter setting;

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

5. No need for batteries, with automatic memory function in case of power failure, ensuring the storage of set parameters and real-time display data; 

6. Photo isolation of input and output, with high voltage protection function, which can be freely connected to any device instrument; 

7. Up to four single-chip computers are used data exchange and processing, to improve the module response speed, thus achieving high-precision servo control; 

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

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

10. It has the function of and negative action selection to meet the actual working conditions; 

11. It has the function of accumulating the number of times the electric actuator has been running, so the user can always know the total number of times the electric actuator has been working; 

12. The non-spark phase change technology is adopted, and theristor components control the output, which truly achieves the modular control of large-power motors and improves the reliability of the product; 

13. ESD emergency event function: 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 power supply, external power supply mode: DC24V AC220V; 

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

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

18 It has the function of adjusting the sensitivity of the electric actuator and setting the control range according to different control needs; 

19. Mechanical torque measuring device: mechanical transmission device is used to measure the load torque of the actuator, which is the method adopted by most traditional actuators. Its characteristics are high measurement accuracy, and reliable. Our company's intelligent electric actuator still uses this method, and the precise value of the torque is transmitted to the CPU for processing, which achieves highprecision torque parameter acquisition. 

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

21. Travel protection function: In the valve opening and closing travel setting and valve opening and closing operation, the servo module protects the travel signal acquisition unit. If the electric exceeds the range, the travel monitoring system sends instructions to forcibly stop the electric actuator and send remote and on-site alarms at this time
