SD non-invasive intelligent electric actuator
Classification of the products
1.Quarter-turn intelligent integration of electric actuators Foot-plate mounted electric actuator Directly mounted electric actuator
2.Linear-turn intelligent integration of electric actuators
3.Multi-turn intelligent integration of electric actuator
SD non-intrusive intelligent electric actuator is the execution unit in industrial automation instrument, it receives from the regulator, PLC, DCS control signal from the computer, such as the completion of automatic adjustment, is indispensable to automatic control system for main equipment. It is widely used in power station, metallurgy, petroleum, chemical mine, light industry, pharmacy, gas power, building materials, transportation and city subway, water supply, sewage treatment and other industries.
Also known as part of the return receipt actuators, general rotation range of 0-90°, the output torque in Nm. Mainly used for: butterfly valve, ball valve, shutter type valve, damper, baffle and plug valve.
Electric Actuators Are Classified According To Control Feature.
1.Integration modulating electric actuator. Analog control signals can be received 4-20ma, 0-10ma, 1-5v, etc. The output Angle is proportional to the input analog signal, and the actuator itself is closed loop and realizes automatic adjustment.
2.Integral switch actuator. Receiving signal switch. Including remote control type and switch type.
3.Linear actuators. It can be divided into modbus, profibus, etc.
Installation dimension can customizable
Foot plate mounted
Foot plate size can be customized
Direct mounted
Control type can be customized
Integration proportional modulating electric actuator
The electric actuator can receive the DC4-20ma analogue controlling signals from the computer,regulator unit ,DCS system.and so on.The turning angle (or displacement)of the output shaft is in proportion to the input signals.Thus the actuator accomplishes its regulation task automatically.
Remote controlled electric actuator
It receives on-off signal or relay signal,enabling the output shaft to stop at any position. Meanwhile output 4-20ma Dc feedback signal.
ON-OFF type or two positions type
It receives on-off signal and the output shaft only can stop at the full-open or full-closed position and output alarm.
Main technical parameters of SD electric actuator
Input signal:4-20mA impedance 250 Ω 0-10mA impedance 200 Ω
Dead area (sensitivity):0.3-3% Continuous adjustable Input channel:one analog current input channel , one set of switch volume channel .

The non-corrosive gas media in the surrounding air must not be used in inflammable and explosive places.
(The explosion-proof products can be found in my company's explosion-proof products'sample.)
voltage and power supply 220V--±10%50Hz
Single phase:220V--±10%50Hz 380V--±10%50Hz
Three phase: 380V--±10%50Hz
*Special voltage, frequency needs to be customized in advance.
Model Preparation Method
Remark: 1.The electric actuator required by the special technology needs to write clearly and concretely in order.
2.When A+RA300/K30HGP model is A+RS, the working torque is 1000Nm, single-phase power supply, the whole travel time is 30 seconds, and foot-plate installation with integration proportional modulatin with the local operation.
