1. Adopting non-invasive design, using infrared remote control or reliable magnetic conduction device body knob for personalized settings and on-site operation, abandoning the traditional through-knob design or waterproof rubber button design, ensuring the waterproof performance and durability of the equipment, and meeting the conditions of outdoor application

2. Multifunctional Chinese character display window, rich display content, easy to understand, users can grasp the basic setting parameters and remote status of the equipment at any time, fault alarm information is clear at a glance, display content includes valve opening, given signal amplitude, operation mode, and Chinese character display screen displays fault information when a fault occurs.

3. Equipped with infrared remote control, non-invasive settings are realized. Users can perform personalized settings on the equipment according to on-site needs without opening the equipment. The end user only needs to open the wiring cover to connect.

4. Infrared remote control can realize non-contact on-site switching of valves.

5. Three-phase power supply automatically detects phase and corrects automatically. On-site installation does not need to care about phase sequence, avoiding the problem of equipment damage due to installation reasons, lack of phase protection, and protecting the safety of the motor.

6. It has complete fault detection functions such as stall and oscillation judgment. After the equipment detects a fault, it will stop working to protect the equipment and the entire system. In addition to displaying the fault information on the display screen, it also sends an alarm to the control system through passive contacts. It has 4 built-in passive contact outputs, including fault, control mode (on-site/remote), open position, and closed position.

7. Precision self-adjustment function, automatically reduce positioning accuracy when oscillation occurs, this function can be turned off or enabled on-site.

8. Rich field-settable working modes: positive and negative action modes can be set, and valve full open, stop, and full close action modes can be set when the control signal is interrupted.

9. Instantaneous reversal protection, for example, when the valve opening action is being executed, the actuator receives the valve closing command, it will stop the action first, and then delay for a preset time before executing the valve closing action to reduce the impact on the equipment.

10. The three-phase power supply is controlled by solid-state relays or contactors, there is no leakage problem, it is safer and more reliable.

11. Fieldbus models can be provided, supporting MODBUS and PROFBUS bus control.

12. Provide RF wireless control models with patented technology, support address operation, realize non-contact one-to-one on-site operation of valves, and display the operating status information of electric actuators on the wireless handheld operator, overcoming the shortcomings of infrared remote control of multiple devices, crosstalk, one-way control, and inability to achieve two-way information transmission.
