The I/o port of PLC requires only 0 and 1 signals. But now you need to connect this port to the pipe pressure sensor. Can you tell me how to convert analog signals of sensors into I/o signals of PLC requirements?. Or is there a pipeline pressure sensor that performs the following functions: when the pressure is 0-p1, there is no output signal; when the pressure is above P1, a 1 signal to the PLC is output. P1 is the manual pressure value set on the sensor. StopHow can I use the configuration software to set the P1 value of the electric contact pressure meter on the host computer?
Add an analog to digital converter. That's all. Buy brands, I do not tell you specific, and I used to work. Buy a pressure switch that should be set.
This is a pressure switch, divided into electronic and electronic structure, can do some pressure meter with a voltage comparator, setting function, structure type pressure switch with bellows and micro switch, can set the alarm point, that you want the pressure set point. He can only pass through two states, and receive a high potential or a ground potential. This way you can access your PLC directly
What you need is a P1 bit signal, which is simple. There are two options for you to choose from:1 、 electric contact pressure meter, it is installed in the field, there are two groups of signals: upper and lower limits, the scene also has instructions. It is simple, intuitive and easy to set up. Do not need any additional facilities (such as A/D converter), etc., the price is low, easy to install is its characteristics.2, of course, pressure sensor, pressure transmitter can be used, if you want to do "a given value" can certainly be used in PLC, because the analog signal sent to them, and PLC certainly need A/D converter and a comparator circuit, is complex (reliability lower) if necessary, can also be used.
