PRODUCT STRUCTURE

1.Handwheel

The sturdy handwheel provides reliable emergency manual operation in the event of power failure.

2. Shell

The high-quality aluminum alloy shell is compact and lightweight. It is coated with a layer of protective material to adapt to extremely harsh environments, and other types of layers are available as needed.

3. Motor

The low inertia and high torque motor allows the motor to quickly reach peak torque after starting, and there is almost no over-limit movement when it is off-excitation. There is a precise temperature switch embedded in the motor coil, which is not affected by the surrounding ambient temperature and keeps the motor in optimal thermal capacity. At the same time, the motor shaft and worm are independent of each other for quick replacement.

4. Worm gear

The worm gear transmission chain is simple, with exquisite structure and constant transmission efficiency. It has a mechanical self-locking function and does not require brakes. The transmission part is filled with long-lasting lubricating oil and can operate for a long time without maintenance.

5. Double-sealed design

The double-sealed design provides a sunflower terminal box that is separated from the control room and sealed. Even if the connection box cover is opened on site, it can ensure the isolation of the inside of the actuator from the outside world, so that moisture, dust, and hazardous gases cannot enter the actuator interior in the slightest, and the internal components are fully protected.

6. Manual/electric switch handle

The manual/electric switch handle can be operated safely at any time. While pressing the handle with appropriate force, slowly turn the handwheel to allow the internal clutch to engage the gear. The clutch will automatically disengage when the motor is energized and in the electrically locked state.

7. Output torque measurement system

A professionally designed useful power measurement system is used as the output torque measurement system. This system is developed from familiar electric energy measurement technology and can obtain accurate and repeatable torque measurement values that are independent of changes in frequency, voltage and temperature.

8. Control panel

The control panel LCD can provide instantaneous, up-to-date status and valve position, with Chinese and English languages available, using an intuitive menu structure to provide calibration and diagnostic information, including torque curves, operation and fault records, motor status, local information and hardware data, etc.

9. Button

The local control "Open"/"Close" buttons and the padlocked "Local"/"Stop"/"Remote" mode buttons all use isolated magnetic transmission Hall effect devices, with no through-shafts and good sealing performance, while eliminating the trouble that can be caused by faulty and fragile reed switches.

COMMUNICATION PROTOCOL

The electric actuator supports Profibus Dp and has the following features:

Support Profibus Dp-V0.Dp-V1.Dp-V2 functional level

High-speed data exchange (up to 1.5Mbit/s - corresponding to approx. 0.3ms/actuator)

Cable length is about 10Km (the length between two actuators is about 1200m)

About 126 devices can be attached

Redundant linear topology as an option

For Profibus Dp, the basic topology is through RS485 segment tree structure, as shown in the figure:

The electric actuator supports Modbus RTU and has the following features:

Fast data exchange (up to 115Kbit/s - corresponding to approx. 30ms/actuator)

Cable length reaches approximately 10km (1200m without intermediate relay between two actuators)

About 247 devices can be attached

Redundant linear topology as an option

For Modbus RTU, the basic topology is through RS485 segment tree structure, the same as Profibus Dp.

The HART communication protocol adopts the frequency shift keying (FREQUENCY SHIFT KEYING, FSK) principle, which is based on the BELL 202 communication standard. Digital signals are represented by two frequencies: 1200HZ represents logic "1", and 2200HZ represents logic "0". Since the average component of the frequency signal is zero during communication, it will not affect the transmission of analog signals. Therefore, the sine waves of these two frequencies can be superimposed on the DC4~20MA analog signal and transmitted simultaneously. In this way, not only the DC4-20MA analog signal can be used, but also the same cable can be used to realize two-way multi-information transmission with digital signals, thus having functions such as modifying the range, damping time, PID parameters, etc., which can improve the operation quality and management efficiency of the system.
