Opening and closing of the output shaft nuts, intelligent when ordering. Fourth, the main technical parameters: 1, the input signal 4 to 20 (special request when ordering) 2, the axial thrust shown in Table 13, the axis travel Table 14, Table 15 full travel time, input resistance 250Ω 7 The basic error of ± 2.5% 8, hysteresis ± 1.5% 9, deadband ≤3% (adjustable) 10, the power supply voltage AC 220V 50Hz 11, use of environmental conditions: a, ambient temperature: 0 ~ 50 ℃ servo amplifier actuator -25 ~ 70 ℃ b, Relative humidity: servo amplifier 10% to 70% actuator ≤95 V. Structure Description: 1, position transmitter, output current signal within the switching actuator. 2, the smart electric actuator intelligent module, 4-20mA input signal to intelligent control valve. According to user needs, this module has the following guide can also be installed in the control box, wiring and specific performance see the module manual. 3, the implementing agency for the field-site installation structure, the gear unit housing is equipped with AC servo motors and conductive plastic potentiometers. There are 4 on the gearbox actuator and reducer coupling and adjust the manual components, an output shaft, a mechanical stopper etc. through levers and springs to achieve. When the gear unit output shaft movement, relying on one end of the spring tension lever is pressed against the end face of the output shaft, thus locator mandrel axial displacement, to achieve the purpose, the output shaft displacement potentiometer value changes of schedule size and Locator resistance linear. At different distances from the fulcrum of leverage to change the itinerary change. Mechanical stopper to press different stroke settings.
