5X00605G01 Emerson redundant system output module
thereby controlling external devices or circuits.
Algorithm Principles
The PID controller, also known as a proportional, integral, or differential controller, takes error as input and calculates the output by weighting the sum of proportional, integral, and differential terms. The PID controller is a very classic controller that is simple and easy to understand, and can be used without the need for an accurate system model. It has a wide range of applications.
There are many introduction materials about PID online, and there are also many easy to understand explanations.
When I introduce the principles of algorithms here, in addition to qualitative analysis, it will also involve some theoretical knowledge, which requires a certain level of professional knowledge in “Automatic Control Principles” and “Signals and Systems”. However, it will not be too in-depth, and they are all simple entry-level knowledge.
Let’s first explain why closed-loop control is necessary, taking controlling the speed of a motor as an example. Before actual control, we may assume that as long as I give the motor an expected speed of 100 revolutions per minute, it will obediently output the result of 100 revolutions per minute. But what about the actual situation? When the motor is unloaded, it may still be able to reach the desired speed, but what if a 10 pound load is added to the motor? Its speed may drop to 80 revolutions per minute, and if the load continues to increase, the speed may continue to decrease.
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 5X00605G01 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.
