Electric Intelligent Module-The Heart Of Electric Control Valve

The upper part is the electric actuator;the lower part is the valve.The actuator controlls the valve action and the module makes the actuator intelligent.

The main specification of module as below:
1. Control accuracy: 0.1%～3.0%(Can adjust by parameter)
2.Electric actuator feedback signal resistance：500Ω～10KΩ
3.Receivable external control signal：4～20mA （1～5V、0～10V、on-off output default value can customized）
4. Input resistance：250Ω
5.Working Mode:
    Forward action mode; Reverse action mode;Interruption mode(input signal  interrupt):OPEN,STOP,SHUT
6.Output of the thyristor（1200V AC，25A）
7.Output signal of the actuator position:
   4～20mA （1～5V、0～10V）
   4～20mA （1～5V、0～10V、on-off output default value can customized）
  Low drift output 4 ~ 20 mADC mapping actuator full close to full open, the output position signal ,the input signal and power double photoelectric isolation; the maximum load capacity is ≤500Ω
8.Environment temperature: -40℃～80℃, relative humidity: ≤90RH%
9.Over temperature protection: When the internal temperature ≥80℃(can be set) , positioner will alarm.
