function

1. Free selection of input signals. Triple display of process quantity, control quantity, and valve position feedback. Square opening and small signal resection can be performed.

2. Choose between automatic or manual startup mode (the output value for manual startup can be pre-set).

3. Two remote manual functions. (EM1, EM2 remote manual function)

4. DFD's hard manual operation function and DFQ's remote manual automatic switching function.

5. Hand automatic state output.

6. The upper and lower limits can be set separately to control the amplitude range of the output.

7. Has motion sensitivity settings.

8. The analog quantity of valve position feedback can calibrate the zero point and full degree.

9. The positive and negative effects of analog input signals and valve position feedback analog output signals can be selected. (Conversion between 0% to 100% and 100% to 0%)

10. The valve position feedback simulates the output reaction to achieve timely tracking of hard manual operation or automatic switching on the control panel.

11. It has a braking function with motor forward and reverse control, and valve position feedback faults can be output through relays.

12. Valve position feedback tracking fault flashing alarm indication (tracking allowable error can be set).

13. Dual analog outputs of valve position feedback analog and control analog.

14. The instrument is equipped with two built-in 41A bidirectional thyristors to directly control the forward and reverse rotation of the actuator. The forward and reverse rotation time of the servo motor can be adjusted from 0.0 to 25.0S. (DFD)

15. Control the forward and reverse rotation of the actuator and automatically cut off the strong current output (DFD) if there is no change in valve position feedback within 15 seconds.

16. We can provide RS485 asynchronous serial communication with multiple hosts, single host, and no host modes. Communication data verification follows the CRC-16 American data communication standard, with high reliability cycling and barcode verification.
