In the entire PLC control system, the most prone location to faults is on site, and the site is most prone to faults in the following aspects.

1. The first type of fault point is also the location with the most faults) in relays and contactors

In the daily maintenance of a certain production line PLC control system, the largest consumption of electrical spare parts is various relays or air switches. In addition to the quality of the product itself, it is mainly due to the harsh on-site environment. For example, contactor contacts exposed to the production environment are prone to ignition or oxidation, gradually heating and deforming until they cannot be used. All on-site control boxes of this production line are made of cabinets with good sealing performance, and their internal components have a significantly longer service life compared to other components that use open cabinets. Therefore, to avoid such faults, high-performance relays should be selected as much as possible and the use environment of components should be improved to reduce the frequency of replacement and reduce the impact on system operation.
