SD intelligent 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.
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 .
Output channel:4-20mA DC impedance > 50 Ω. The input channel is isolated from the output channel.
Output torque and travel.
Linear-turn: 2000N-25000N travel 10/16/25/40/100mm
Quarter-turn: 100-40000Nm travel 90°
Multi-turn: 40-400Nm travel 1-50 circle
Basic error:±1%;±1.5%
Return difference:≦ ±1%
Damping characteristics:No oscillation (zero period oscillation)
Level of proection: IP67
Operation environment:
1. temperature: -28--+70
2.humidity: ≦95%
3.shake: frequency 10-100Hz strenth, 0.5 times of acceleration of gravity
4.impact: <5g
5. barometric pressure:72.5-106KPa
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.
Special customized valve
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.
