Abstract
Description
Technical Field
[0001] This utility model relates to the field of controller technology, and in particular to a programmable controller. Background Technology
[0002] Programmable logic controllers (PLCs) employ a type of programmable memory to store programs and execute user-oriented instructions such as logic operations, sequential control, timing, counting, and arithmetic operations. They control various types of machinery or production processes through digital or analog inputs / outputs. However, existing medium-sized PLCs, including their housings, are prone to overheating during operation, resulting in a short lifespan. Furthermore, the limited number of wiring ports on the housing is insufficient for current applications, hindering widespread adoption. Commercially available PLCs typically use power connectors for grounding, which leads to long grounding paths for modules farther from the power connector when multiple modules are installed, resulting in poor grounding performance. Therefore, we have redesigned a new PLC. Utility Model Content
