SKD series electric actuator is specially design for the cement industry, which can not only meet the multi-turn but also output large torque.It incepts 4-20mA an alogue signal from the modular or the computer,outputs the torque or the thrust and automatically operates the actuator to perform the automatic modulating.
1. Input signal：4-20mA impedance 250 Ω,0-10mA impedance 200 Ω
2. Dead area (sensitivity)：0.3-3% Continuous adjustable
3. Input channel：one analog current input channel , one set of switch volume channel
4. Output channel：4-20mA DC impedance > 50 Ω. The input channel is isolated from the output channel.
5. Output torque and travel. Multi-turn 40-400N, travel 1-50 circle
6. Basic error：±1%;±1.5%
7. Return difference:≦ ±1%
8. Damping characteristics: No oscillation (zero period oscillation)
9. Level of proection: IP67
