1. This series of electric actuators adopts a combined structure in mechanical design, and the product components are universal, standardized, and serialized, so that the product can form a variety of series and specifications through the combination of mechanical, motor, microelectronic control circuit, and different functions. It has strong versatility and reduces a large number of spare parts in product maintenance.
2. The operating status of the electric actuator is displayed digitally on-site, with a given signal and valve position signal, and the display of 0-100% digital quantity corresponds to a 4-20mA signal. The operating status of the actuator can be displayed intuitively on-site.
3. The given control signal and the valve position output signal are isolated and do not share a common ground, which enhances the anti-interference function.
4. Non-invasive, infrared remote control operation.
5. Single-phase and three-phase electric actuators use zero-crossing trigger power devices and contactless power output to control the operation of servo motors.
6. Add the function selection of remote control operation and on-site operation, and realize on-site (on-site), remote control switching and on-off conversion operations through Hall switches.
7. The angle and travel distance of the angular travel and linear travel actuators are not constrained by 90 degrees or fixed travel distances. Within the range allowed by the mechanical design, they can meet the angle or travel distance requirements required for on-site installation.
8. Signal break, lock, and alarm functions. The actuator performs random self-checks during operation and has a running status diagnosis function. When a signal break occurs, the actuator can be pre-operated to the emergency setting position (fully open, fully closed, stop, or specified position) according to the system process requirements.
9. Automatically determine the starting current and over-torque condition of the servo motor. After the torque sensor detects the over-torque signal, the forward and reverse over-torque alarm outputs can be randomly configured to the control room according to the system process requirements.
10. Dynamic electric braking. After the position sensor measures the travel balance point, the electronic brake is applied to the exact position. The forward travel, reverse travel, and braking time can be independently set according to different torque outputs, overcoming the defects of mechanical friction braking.
11. The three-phase electric actuator has the function of automatic phase sequence correction and phase loss detection, so that the actuator always keeps the correct rotation direction. When a phase loss occurs, it will automatically alarm, the forward and reverse indicator lights of the power module will flash at the same time, and the motor will stop working. The alarm signal will be output to the control room to prompt the operator to take early treatment measures, and it will run normally after recovery. The random number setting range is 0-20, the minimum value is 0, the initial value is 1 without braking, and the final value is 800ms. It can be intuitively set according to the torque output of different shafts.
