Application
The CPM1A series micro controllers solve both basic and semi-complex applications. The brick style models include DC inputs/transistor or relay outputs to meet your design requirements. The base I/O for the CPUs ranges from 10, 20, 30, and 40 I/O points with maximum expansion to 100 I/O. Specialized expansion modules include mixed analog I/O, temperature sensor inputs and serial communications.
PLC technology is widely used in the control fields of various production lines, such as the automotive industry, electronics industry, machinery manufacturing, etc. The PLC module can realize automatic control of various production processes on the production line, such as automatic assembly, processing, packaging, transportation, inspection and other operations, improving production efficiency and reducing labor costs. For example, in the body welding production line in the automobile industry, the use of PLC can realize automatic control and adjustment of body welding, improve production efficiency and quality, and save labor costs.
PLC can be used in various energy systems, such as water pump control, wind power generation control, solar energy control, generator set control, etc., to achieve efficient use of energy and automatic control of energy systems. For example, using PLC for solar panel control can realize automatic tracking of solar resources and automatic control of solar panels, optimize solar energy utilization efficiency, and reduce electricity costs.
