MP200d  Smart Positioner
 
1 Main Functions            
The MP200d  smart valve positioner can be applied to linear or rotary actuators. It is a two-wire device that the input signal of 4-20 mA DC is also used as the power supply. Additional wires are required for position feedback and switch outputs. The positioner can be configured as single-acting or double-acting.            

• The travel of the actuator drives the feedback axis of the positioner and rotates the position sensor, which is converted into electrical signals.            
• The input signal of 4-20 mA DC and actual position are transmitted to the microprocessor through A/D conversion. The microprocessor uses these data to calculate the position deviation and the output with an advanced PID control algorithm.            
• The position controller output is used to drives an I/P module that connected to a pneumatic relay that fill air to or exhaust air from the valve actuator, causing valve to move toward the desired position.  

 
2 Technical Parameters            

1. Analog input signal: 4-20 mA DC. Users can choose 4-12 mA or 12-20 mA range for split control application.            
2. Analog feedback signal (optional): 4-20mA DC [external 12-24V DC power supply in the loop].            
3. Switch output (optional): power supply voltage of 24V DC.            
4. Transmitter analog input signal PV (optional): 1-5V DC.            
5. Instrument-grade air supply: free from oil, moisture, and dust. (The maximum particle size: 5um, maximum particle density: 5mg/m3; maximum oil concentration: 1mg/m3; Dew point: 10K below ambient temperature. Supply pressure: 0.14-0.7 MPa. (Notes: not exceeding the maximum operating pressure of the actuator).            
6. Air consumption: < 0.04 kg/h (independent of supply pressure).            
7. Acting: Direct (air-to-open, signal-to-open): the input signal 4-20 mA DC corresponds to the valve position 0-100%. Reverse (air-to-close, signal-to-close): input signal 4-20 mA DC corresponds to valve position 100-0%.            
8. Characteristics:

• linear
• 1:25 equal percentage  
• 1:50 equal percentage           
• Quick-opening
• Custom (with HART option)            

9. Accuracy of current sampling: <0.1%.
10. Valve position dead zone adjustment: 0%-5.0%.             
11. Valve position control cycle: 15 Ms.            
12. Valve cutoff low range: 0-20% (if the signal is lower than the cutoff low value, the positioner moves the actuator to the tight shutoff position.            
13. Environmental adaptability:            Ambient temperature: - 25 ~ + 70 C (standard temperature type); - 40 ~ + 85 C (wide temperature type)  

Ambient temperature: - 40 ~ + 85 C storage and transportation  
Relative humidity: <90% (short time 95%) without condensation.      

14. Explosion-proof: Ex d II CT6 Gb.
15. Housing material: Die Cast Aluminum Alloy.
16. Electrical connection: NPT 1/2; PT, PF, and M threads are optional.
17. Pneumatic connection: NPT 1/4; PT, PF, and M threads are optional
