function

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 are faults such as resistance, coupling, or wire breakage, the analog outputs of control and process variables can be selected as 0%, 100%, or upper limit amplitude and lower limit amplitude.

5. Tracking the zero point and full degree of the input signal can be calibrated.

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

7. Square opening and small signal resection can be performed.

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 on the basis of maintaining the first control variable.

11. The measured value and the set value display can be added or subtracted.

12. PID parameter self-tuning or independent self-tuning of P parameter.

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

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

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

16. Four switch control outputs. It can achieve methods such as relocation 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 regulator is equipped with a built-in 41A bidirectional thyristor to directly control single-phase resistive loads with AC power below 2KW or output three sets of synchronous signals triggering bidirectional thyristors with power below 500A. (Note: It should be a resistive load)

19. 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.
