SD series Multi-turn electric actuator is the terminal control device in industrial process measurement and control system. It can transform the system control signal into the output displacement (quarter turn displacement, multi-turn displacement or linear displacement), output torque or thrust to control the position of closure member and other modulating device in the valve. Thus the controlled medium will work in condition regulated by the system.
1. Input
signal:4-20mA Impedance 250Ω,0-10mA Impedance 200Ω.
2.
Deadline:0.3-3% Continuously adjustable.
3. Input
passage:One for the analogue current input and one for the on-off input.
4. Output
signal: 4-20mA DC Impedance < 500Ω The input passage and the output passage
are isolated.
5. Rated load:6400N;Rated travel:10、16、25、40、60mm
6. Basic error: ±1%;±0.5%
7. Deviation≤±1%
8. Damping
characteristic:No-oscillating
9. Protecting
class: IP 67
10. Operating
enviroment:
1)
Temperature:-25℃—+70℃
2) Humidity:≤95%.Vobration:Frequency,10—100Hz.
3)
Intensity,0.5time acceleration of gravity
4) Shock:<5g
5) Atmospheric
pressure:72.5—106Kpa0
6) There is no
corrosive gas round the air. 1t couldn't he used in an inflammable and
explosive site except for the explosion-proof model product.(The explosionproof
model product please see the sample of the explosion-proof model product).
11. Power
supply: Single phase:220V±10% 50Hz; Three-phase:380V 50Hz; The technical
parameters of the remote model (ON-OFF model) don not conclude the first item
and the second item. The other items are the same as the proportional
modulating model.
