3500/22M 288055-01 Transient Data Interface

3500/22M 288055-01 introduced mainly through the power supply and signal lines, usually called conducted interference. This kind of interference is more serious in our industrial site, there are mainly the following three categories:
The first category is interference from the power supply. Practice has shown that the power supply interference caused by the introduction of many PLC control system failure, I encountered in a project debugging, and then replace the isolation performance of the higher PLC power supply problem to be solved.

3500/22M 288055-01 system’s normal power supply are powered by the grid, due to the wide coverage of the grid, it will be subject to all the space electromagnetic interference and the induction of voltage and current on the line, especially the changes within the grid, switching operation surge, large power equipment starting and stopping, AC and DC drives caused by harmonics, grid short-circuit transient impacts, etc., are transmitted to the original side of the power supply through the transmission line. PLC power supply usually uses isolated power supply, but because of its mechanism and manufacturing process and other factors make its isolation is not ideal. In fact, due to the presence of distributed parameters, especially distributed capacitance, absolute isolation is impossible.

3500/22M 288055-01 is interference introduced from the signal line. With the PLC control system connected to the various types of signal transmission lines, in addition to the transmission of effective information of all kinds, there will always be external interference signal intrusion. This interference mainly has two ways: one is through the transmitter power supply or common signal instrumentation power supply string into the grid interference, which is often ignored; the second is the signal line by the space electromagnetic radiation induction of interference, that is, the signal line on the external induction interference, which is often very serious.
