Intelligent Model Electric Actuator

1,Classification and uses of the products The electric actuator is an executing unit in the industrial automatic instruments and the main indispensable device of the automatic controlling system, it incepts the signals from the regulator, PLC and DCS etc. controlling computer to automatically perform the regulating action. It is extensively used for the fieds of power station, metallurgy, chemistry, mine, pharmacy, thermal power, architecture material, transportation, urban subway, water and sewage treatment etc. SD,SR and SM series electric actuators adopt combined structure.They have the full types, small volume, ethereal weigh and convenience mounting mode, reliable performances and easy for adjustment and maintenance. 2,The main technical parameters of the electric acuator 1.Input signal:4 20mA Impedance 250Ω,0 10mA Impedance 200250Ω. 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.Output torque and travel: Quarter turn: 100Nm-12000Nm Travel 90 degrees Linear turn : 100Nm-12000Nm Travel 90 degrees Linear turn: 2000Nm-25000Nm Travel 10,16,25,40,60,100mm Multi-turn: 40Nm-900Nm Travel 1-50 circles. 6.Basic error:±1%:±0.5% 7.Deviation: ≤±1% 8.Damping characteristic: No 9.Protecting class: IP 67 10.Operating environment: Temperature:-25°C-+70°C 11.Power supply: Single phase:220V±10% 50Hz Three-phase: 380V ±10% 50Hz±1% 460V ,480V 60Hz±1% The technical parameters of the remote model (ON-OFF model) do not conclude the first item and the second item. The other items are the same as the proportional modulating model.
