Certified CE Certified 4-20madc Electric Actuator in Great Demand

 

M03/04 series intelligent electric actuator is build-in servo controller, the execution unit instrument with output angle stroke. Mainly used to rotation regulating mechanism such as control butterfly valve, globe valve, plug valve and damper etc. and realize automatic control of process. Widely apply to industry pipeline fluid control system such as electric power, metallurgy, petrifaction, light industry and sewage treatment etc..
It receives 4~20mAd.c. signal of the upper control unit or control of passive switch signal, output 0~90° corner and corresponding torque, drive opening or closing of rotary regulating mechanism. It has advantages of small cubage, light weight, strong function, convenient operation, tighten structure, stable operation, high precision, flexible reaction etc.

Main technical parameters

1. Input signal: M03 series:Three active 24Vd.c. or passive switch signal,that is remote/local switch, opening operation, closing operation. High level or connection is valid, high level 18-30V, low level -2V~+2V. Digital min. lasting pulse width is 50ms.Operation mode can be inching or self-holding mode.

                        M04 series: Except receiving same digital input signal with M03 series, it also receives 4~20mAd.c. analog signal control.
2. Output signal:a. Passive switch,four:there are trouble alarm, remote/local working condition, full-open of valve position, full-close of valve position. It's connection with output and it's breaking without output. Capacity:220V,3Aa.c..
                          b. Optional analog signal output:4~20mAd.c.,load capacity 0~750Ω.
3. Orientation precision:±1.5%F.S.;
4. Dead zone:(0.5%~5%)F.S.;
5. Motor working mode:S4;
6. Power supply :three-phase 380V±10% ,50Hz±1% or single-phase 220V±10% 50Hz±1% ;harmonic content:less than 5%;
7. Environmental condition :
    Environmental temperature: -25ºC~+70ºC;
    Relative humidity: less than or equal with 95%;
    Atmosphere pressure:86kPa~106kPa;
    No corrosive medium and flammable substance in environmental air.

Overall structure and operation principle

·Operation principle: Drive skew wheel via motor, the meshing of skew wheel and clutch drive the transmission of worm and second stage skew wheel, finally finish the external transmission output.
·Basic characteristic:  Output is part turn mode, the structure is tighten and weight is light.
·Cover: Excellent aluminum alloy, light weight and high intension. Painting outside and anti-erosion is strong.
·Motor: Adopt sensitive motor, high torque and low inertia and build-in overheating protector to protect the damage of overheating.
·Manual unites clutch system: Put the clutch handle, do manual operation by handwheel arm. After loosen clutch handle, clutch reset to electric position automatically. Electric and manual operations are sole.
·Stroke switch: It is used to limit the operation range of actuator, simple regulating units can set the position of stroke switch accurately and conveniently.
·Torque switch: Use torque sensor which can check mechanical displacement to monitor torque output of actuator continuously. Supply overload protection to prevent the damage of valve and actuator from overload.
·Position self-lock: With self-lock function, no need to use motor or other stop way.
·Position indicator: Position indicator installed on the output center shaft, synchronized with output, you can observe the movement position directly.
·Connection and installation: Output installation flange dimension should according to ISO5211 standard, driving sleeve can disassemble and process according to requirement, strong adaptability. The actuator can be installed uprightly or horizontally.
·Wiring terminal: Collocation is compact and reasonable, big terminal pressure, shockproof and stable wiring.
