It not only brings together most of the functions of various adjustment instruments in the current automatic control system, but also integrates circuits such as CPU, I/O interface, EPROM and D/A conversion, supplemented by a software system that draws on the strengths of others, carefully compiled, and repeatedly debugged. Can make you handy in the production process, such as wing arm finger.
Features
1. Twenty kinds of input signal options.
2. Three-fold display of process quantity, given value and control quantity.
3. The selection of the positive and negative effects of the PID regulator.
4. In the event of interruption, burnout, or disconnection, the analog output of the control quantity and the process quantity can be selected as 0%, 100% or the upper limit value and the lower limit value.
5. Tracking the zero point and full scale of the input signal can be calibrated.
6. Intelligent sound and light alarm, dual timer or counter function.
7. Prescription and small signal excision can be performed.
8. Arbitrary selection of valve position feedback signal (various analog inputs).
9. External setpoint input can be realized (EM2 function).
10. The upper limit and lower limit output control range of the control quantity can be set separately. The split-range PID control can be realized, that is, two split-range control quantities are generated on the basis of maintaining the maximum control quantity.
11. The measured value and set value display can be added and subtracted.
12. PID parameter self-tuning or P parameter independent self-tuning.
