Application scenarios
Industrial production line monitoring: In industrial production lines such as automobile manufacturing and electronic product production, various sensors can be connected, such as photoelectric sensors to detect the passage of products, proximity sensors to detect the position of robotic arms, etc. These switch signals are input into the PLC to achieve automated control and monitoring of the production process, ensuring the normal operation of the production line and product quality.
Energy management system: In the energy fields of electricity, petroleum, chemical engineering, etc., it is used to collect status signals of on-site equipment, such as valve opening and closing status, pump operation status, generator fault signals, etc., to provide basic data for the energy management system for energy scheduling and equipment maintenance.
Intelligent building automation: In intelligent buildings, it can be used to monitor the on/off status of doors and windows, the on/off status of lighting systems, the operating status of air conditioning systems, etc., to achieve centralized control and management of building equipment, improve the intelligence level and energy utilization efficiency of buildings.
Water treatment system control: In water treatment plants, various water quality sensors, liquid level sensors, water pumps, and valve control signals can be connected to achieve automated control of the water treatment process, ensuring water quality standards and stable system operation.
