I. Overview DKJ type angular stroke electric actuator is the execution unit in DDZ-II and III series instruments. It is used with DDZ-II and III type control unit instruments. It is powered by AC power and accepts a unified standard signal of 4~20mA. Dc (or 0 ~ 10mA, dc), the input signal and the feedback signal of the position transmitter, after the comparison of the servo amplifier, the output switch signal, drive the motor, after mechanical deceleration, convert the input signal into the corresponding output shaft angular displacement : Automatically operate the damper flapper, butterfly valve, ball valve and other devices to complete the automatic adjustment task of the system: it is widely used in the regulation system of industrial sectors such as power station, metallurgy, petroleum, chemical, machinery, light industry, textile, food and medicine. . Second, the model meaningThird, the conditions of use1. Input signal: switch positive and negative signals (220VaC).2, the output signal: DC 4-20mA.3, the effective displacement of the shaft: 0--904. Conversion error: no more than ±0.1% FS.5. Limit setting range: the limit is 0-80%; the opening limit is 20-100%.6, long-term stability: ± 0.1% FS.7, power: AC220V ± 20%.8, ambient temperature: -40-75 ° C9, environmental humidity: ≤ 95% Fourth, functional characteristics
● Position transmitter adopts gear type transmission to ensure reliable and accurate limit
● Precision conductive plastic potentiometer with angle indication is easy to debug and easy to understand
● The circuit adopts epoxy resin packaged module structure and is aging at high and low temperature. Ensure stable and reliable
● Motor adopts outdoor type servo motor with overload protection.
