1. Various analog inputs or frequency inputs.

2. Triple display of process quantity, given value, and control quantity.

3. PID regulator positive and negative action selection. Manual automatic bidirectional undisturbed switching.

4. When there is a fault of resistance, coupling, or wire breakage, the analog output of the control quantity and process quantity can be selected as 0% or the upper limit amplitude or lower limit amplitude.

5. The zero and full scale of the tracking input signal can be calibrated.

6. Intelligent sound and light alarm, dual timer or counter function.

7. Can perform square root and small signal resection.

8. Valve position feedback signal can be freely selected (various analog inputs).

9. Can achieve input of external given values (EM2 function).

10. The upper and lower limits of the control quantity can be set separately to output the control range. It can achieve split range PID control, which generates two additional split range control variables while maintaining the control quantity.

11. The measured values and set values can be displayed with addition and subtraction operations.

12. PID parameter self-tuning or P parameter * * * automatic self-tuning.

13. 8 sets of set values and storage and retrieval of P, I, and D parameters.

14. Control quantity tracking feedback quantity (EM1 function), can achieve manual/automatic bidirectional disturbance free cutting. Internal given value displacement (SB function).

15. Can achieve ratio control. Ratio control formula: given value SP=A x external given value+B (A is the ratio coefficient).

16. 4 switch quantity control outputs. It can achieve methods such as repositioning and associated alarms.

17. Two or three analog outputs: 0-10mA or 4-20mA.

18. The 50HZ synchronous bidirectional thyristor zero crossing interpolation control algorithm is used to achieve optimized control of each sine wave, avoiding high-order harmonic pollution of the power grid caused by high-power loads. The intermittent PID controller is equipped with a 41A bidirectional thyristor to directly control single-phase resistive loads below 2KW or output three sets of synchronous signals that trigger bidirectional thyristors below 500A. (Note: should be a resistive load)

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