1. Overview
intelligent electric actuator is used to drive various types of pipe valve device, widely used in power plants, metallurgy, petroleum, chemical industry, water supply, food processing and other fields.
using Twido programmable controller for the electric actuator of the master controller. Twido modular controller s small size is its stand, and finally select the key. By Twido PLC control of various input signal processing, the implementing agency can accurately be used to cut-off valve, gate valve, throttle valve, gate valve and other control. Twido PLC supports Modbus protocol, field bus control network access. Flash memory built using Twido can record data in order to find the number of valve operations, history and so the maximum valve torque.
2. System Description
the intelligent electric actuator products set the main controller, absolute encoder electronic travel control and electronic torque controller, human-machine interface as a whole. Can be off and closed loop control system in the final control elements (valves) control, support for network transmission.
requests the main controller small, powerful, energy and absolute encoders electronic travel control and electronic torque controller, human-computer interface together. Man-machine interface for the Chinese menu, to set the parameters and status display. Master controller to the preservation of historical data.
Absolute encoder electronic travel control and electronic torque control their own development by the Power Station Auxiliary Equipment Works.
man-machine interface for the liquid crystal display, from a company for its custom of Wuxi, the Chinese menu to make on-site commissioning man-machine interface more intuitive. To the selected parameters and torque, stroke, opening, accurate way to set remote control and can display Phase, motor overheating, excessive torque and other fault conditions.
3. Conclusion
and Schneider through the cooperation of customers to Twido PLC integrated within the actuator. Twido s smart and powerful features is the size of the implementing agencies to ensure successful development. The product not only strengthened the auxiliary plant in our industry leading position, further enhances the challenge of intelligent electric actuators made imported products with the type of confidence in the implementing agencies. To the interests of customers is comprehensive. Schneider s brand image while also help customers to better explore the market. The implementing agencies have been widely used in electric power industry, a major project.
