1、 Overview

Intelligent PID regulator produced by Ouwei Instrument. There are no adjustable components inside this instrument, and no auxiliary function modules are required. All parameter settings, function mode selection, and accuracy calibration of analog input and output are achieved through the buttons on the instrument panel. In order to use the instrument correctly and reasonably, and fully utilize its various functions, please read the subsequent sections of this manual carefully before use. The instrument has been correctly set according to your ordering requirements before leaving the factory. If you want to change the corresponding setting parameters, it must be operated by technical personnel familiar with the industrial control site after fully understanding the performance of this instrument. If you have any new suggestions or ideas during use, please inform our company in a timely manner so that we can provide you with better products.

2、 Main performance

1. More than twenty input signals can be selected (measurement input signals can be square root and small signal cut).
2. Multiple displays including process quantity, given value, control quantity, valve position feedback quantity, etc. The display of measured values and given values can be added or subtracted.
3. Selection of positive and negative effects for PID regulation of control variables.
4. The upper and lower limit amplitudes of the PID regulator can be independently set.
5. PID parameter self-tuning or independent self-tuning of P parameter.
6. Power on automatically or manually, and the manual output value can be pre-set.
7. Manual automatic bidirectional disturbance free switching and manual status indication and output.
8. Input the switch quantity SB function to control the displacement of the given value.
9. Two or three analog outputs.
10. The instrument can have up to six switch outputs, and one of the switch outputs can be set to monitor the other two switches selectively, achieving intelligent sound and light alarm function with silencing time.
11. Remote control of EM1 and EM2.
12. The 50Hz synchronous bidirectional thyristor zero crossing compensation control algorithm is used to achieve optimized control of each main wave, avoiding high-order harmonic pollution of the power grid caused by high-power loads.
13. The intermittent PID regulator instrument can directly control single resistive loads with AC below 2KM or output 3 sets of synchronous signals triggering bidirectional thyristors below 500A for users with built-in 40A bidirectional thyristors.
14. 8 sets of given values SP and P, I, D parameter storage and calling.
15. The control output of the remote switch quantity control regulator is PID regulation mode or hold state, with bidirectional disturbance free switching.
16. Set the given values and PID parameters online without disturbance.
17. The control input of the remote switch quantity control regulator is PID regulation mode or tracking state, with bidirectional disturbance free switching.
18. At the same time as PID regulation or positional control, the instrument can define one or two relays to achieve a dual channel timing function with a timing accuracy of 10-5 for each channel up to 100 hours.
19. Fault control output can be achieved after resistance, disconnection, and disconnection, as well as fault control output for valve position feedback blockage or disconnection (1-5V, 4-20mA).
