function

1. Various analog or frequency inputs.

2. Multiple displays including process quantity, given value, control quantity, valve position feedback quantity, etc.

3. The measured value can be added or subtracted from the given value.

4. Servo control PID regulator positive and negative action selection.

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

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

7. 2 or 3 analog outputs are: 0-10mA, 4-20mA.

8. 8 alarm control modes to choose from.

9. Braking function with motor forward and reverse control. The valve position feedback fault can be output by a relay.

10. Input the switch quantity SB function to control the transfer of the given value.

11. Built in 41A bidirectional thyristor directly controls the electric actuator.

12. The measurement input signal can be square root and small signal cut off.

13. Power on automatically or manually, maintain the position or manually preset the power on position. Valve position feedback disconnection automatically enters manual mode (please specify when ordering).

14. It can achieve intelligent sound and light alarm with silencing time, intelligent timer or counter function.

15. PID parameter self-tuning or independent self-tuning of P parameter. 8 sets of set values and P, I, D parameter storage and retrieval.

16. Remote manual automatic status control. Remote control console hard manual operation; The control output of the remote switch quantity control regulator is in PID regulation mode or in hard manual operation mode on the console, with bidirectional disturbance free switching; Remote servo PID controller control mode or direct control mode by upper computer.

17. When the input signal fails in the direct control mode of the upper computer, it automatically switches to its own PID regulation control mode; When directly controlled by the upper computer, the servo controlled PID regulator automatically tracks the input signal of the upper computer.

18. 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.
