RJDWQ-2012S
Specifications
Electric actuator RJDWQ-2012S electric valve position regulator. Control the motor that directly controls the electric actuator to move in the direction of reducing the signal difference until the signal difference is less than the control sensitivity value.
Product display
At the same time, the off signal indicator light (red indicator light) above the control is on, and the electric actuator RJDWQ-2012S electric valve position regulator. The automatic indicator light (red indicator light) flashes. At this time, the control can be switched to manual state through the A/M key. At this time, the manual indicator light (green indicator light) on the control is on.
The control is installed inside the electric actuator and directly accepts the standard 4~20mA current control signal or switch signal from the DCS control system or other host computer control system. The potentiometer signal inside the actuator is used as the valve position signal sensor. The valve position signal The control signal is compared internally with the electric actuator control module RJDWQ-2012S. When the compared signal difference is greater than the control sensitivity value, the control directly controls the motor of the electric actuator to move in the direction of reducing the signal difference. Until the signal difference is less than the control sensitivity value. There is a special identification system inside the control that is responsible for monitoring disconnection, the electric actuator control module RJDWQ-2012S. Once an input signal failure occurs, the control will immediately stop the strong current output to the electric actuator and maintain the analog output before the disconnection. , at the same time, the off signal indicator light (red indicator light) on the control is on, and the automatic indicator light (red indicator light) flashes. At this time, the control can be switched to the manual state through the A/M key. At this time, the manual indicator light on the control ( Green indicator light) is on, and the electric actuator is controlled in manual mode. In manual mode, the automatic indicator light stops flashing, and the off signal indicator light is still on. Only after the fault is eliminated, the off signal indicator light goes off, and the electric actuator control module RJDWQ- 2012S. Control can enter normal working condition. When the valve position signal sensor is disconnected, the control will immediately stop the strong current output to the electric actuator, and the electric actuator will stop at the current position. At the same time, the automatic indicator light on the control will flash, allowing users to quickly find faults.
