Ruiji-R series split-type actuator

1、Overview

R series intelligent split electric actuator is mainly composed of two parts: electrical part and mechanical part. The mechanical part can choose multi-rot actuator or angular stroke (partial rotation) actuator. The electrical part can quickly set, check and inquire parameters without opening the cover through an independent setter. Theuator adopts a graphic dot matrix LCD display, which displays the working status and alarm of the actuator such as torque, valve position, limit setting in the form of, English, numbers and graphics. It supports field bus communication technology such as MODBUS, PROFIBUS, FF and HART.

3、 Function and performance and features introduction

1.The R series split-type actuator automatically detects the phase sequence of the three-phase power supply connected to the power terminal and through appropriate logical operation, it decides which AC contactor to energize when the actuator is operating, so as to ensure that the motor is connected to the phase sequence. Without the automatic phase sequence adjustment function, it is possible to damage the valve due to incorrect wiring phase sequence. With the automatic phase sequence adjustment function, wiring of the actuator power supply can ignore the phase sequence. 2. Valve position detection uses a magnetic absolute position encoder, and the output shaft drives the magnetic position encoder to rotate, and the generated encoded signal is input into the main control chip to calculate the current valve position value, which is used as the valve position display. Since the absolute encoder obtains the absolute information of the valve position, power failure and interference will not affect it, so the valve position obtained is always correct. . Torque detection, intelligent electronic torque measurement and control technology, makes the torque protection value can be adjusted linearly by the setter, with high precision and convenient use And it excludes mechanical wear and maintains stability for a long time. 4. The R series split-type electric actuator has a total of 3 wiring terminals for mechanical part and the electrical part. The wiring terminal of the mechanical part is #1 wiring terminal, the wiring terminal on the left side of the electrical part is # wiring terminal, which is connected to the mechanical part, and the wiring terminal on the right side of the electrical part is #3 wiring terminal, which is used for connection of power lines and signal lines (connection with the control system).
