Problems solved by technology
Domestic programmable relays mainly rely on imports. The programming mode of programmable relays designed abroad adopts the ladder diagram programming mode. This programming mode requires professional training and masters relevant control symbols and control statements before programming. Overall programming The process is complex, difficult to operate, and the threshold of use is high, which also leads to the maximum expansion of its user group; and the input and output interfaces of this type of programmable relay are not only single, but also extremely limited, and the expansion ability is also poor , the scope of application is limited

Description
technical field [0001] The invention relates to the field of relays, in particular to a multi-channel programmable relay. Background technique [0002] Programmable relays have the characteristics that users can program and design logic control processes freely. By writing logic control programs in the product, scene applications such as parking lot access control, city lighting night scene control, and automatic agricultural irrigation can be realized. Domestic programmable relays mainly rely on imported and foreign programmable relays. The programming mode adopts the ladder diagram programming mode. This programming mode requires professional training and mastering the relevant control symbols and control statements before programming and overall programming. The process is complex, difficult to operate, and the threshold for use is high, which also leads to the fact that the scope of its user group cannot be expanded to the maximum extent; and the input and output interfa...
