Description
1C31169G01 Emerson redundant system output module
thereby controlling external devices or circuits.
Since the error and controller output are both time-varying, we assume them to be err (t) and U (t), respectively, so that we can derive the formula for continuous PID
U(t)=Kp∗err(t)+Ki∗∫err(t)dt+Kd∗derr(t)dtU(t)=Kp∗err(t)+Ki∗∫err(t)dt+Kd∗derr(t)dt
After performing proportional, integral, and differential operations on err (t), weighted summation is performed to obtain the output U (t). Why do we need all three at the same time? Let’s qualitatively analyze the meaning of each item——
Firstly, assuming that both Ki and Kd coefficients are 0, the formula changes to
U(t)=Kp∗err(t)U(t)=Kp∗err(t)
What would the output result be if the output quantity varied proportionally with the size of the error? (Blue line represents output, yellow line represents expectation, purple line represents error)
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 1C31169G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
