Power Requirements
Usually powered by DC power supply, with common voltage specifications possibly being 24V DC to adapt to power configurations in industrial environments.
Types of Communication Interfaces
May include Ethernet interfaces, RS-485 interfaces, etc., to meet different communication needs. The Ethernet interface may support 10/100Mbps adaptive speed, and the RS-485 interface follows corresponding electrical standards and communication protocols.
Specifications of I/O Interfaces
Digital input interfaces may support standard TTL levels or industrial-standard 24V levels.
Digital output interfaces may have certain driving capabilities to directly drive relays or other loads.
Analog input interfaces may support multiple signal ranges (such as 0-10V, 4-20mA, etc.), and analog output interfaces also have corresponding signal range and accuracy requirements.
Operating Temperature Range
Considering the diversity of industrial environments, its operating temperature range may be wide, such as -40°C to +70°C, to ensure stable operation under different environmental conditions.
Protection Level
To adapt to harsh industrial environments, it may have a certain protection level (such as IP20 or higher) to prevent dust and water droplets from entering the device and affecting its normal operation.
Data Collection and Processing
Collect signals from sensors or other devices through input interfaces, such as analog signals (temperature, pressure, flow, etc.) or digital signals (switch status, pulse signals, etc.). Analog signals are subjected to analog-to-digital conversion (A/D conversion) and processed after being converted into digital signals, while digital signals are directly subjected to logical judgment and processing. According to preset algorithms and programs, the collected data is analyzed, calculated, and processed (e.g., data filtering, linearization, threshold judgment, etc.) to extract useful information.
Control Decision-Making and Output
Generate corresponding control signals based on processed data and preset control strategies (such as PID control algorithms or other logical control algorithms). Send control signals to actuators (such as motors, valves, relays, etc.) through output interfaces to achieve control and adjustment of equipment, so that the system reaches the expected operating state.
Communication and Interaction
Communicate with other devices or systems through communication interfaces, follow corresponding communication protocols, send collected data and equipment status information to the upper computer or other controllers, and simultaneously receive instructions and parameter settings from the upper computer or other devices to realize information interaction and collaborative work between devices.
Industrial Automation

Water Treatment
Applicable to water treatment facilities such as sewage treatment plants and waterworks, and used for automated control of water treatment processes (such as controlling the start/stop of water pumps, opening/closing of valves, monitoring water quality parameters, etc.).
Pharmaceuticals
In the pharmaceutical production process, it can be used to control production equipment and monitor production environment parameters to ensure the quality and safety of drug production, in line with relevant pharmaceutical industry standards and specifications.
Building Automation
Used in building management systems to realize control and monitoring of systems such as lighting, air conditioning, ventilation, and security, improving building comfort and energy efficiency.
Transportation
Can be used to monitor and control traffic signals, tunnel ventilation and lighting systems, intelligent transportation equipment, etc., to ensure the safe and smooth operation of transportation systems.
Medical
In the medical field, it can be used to connect and control various medical devices (such as medical robots, experimental instruments, life support systems, etc.) to realize automated control and data collection of medical devices.
Laboratories
Suitable for scientific laboratories, and can be used to control experimental equipment and collect experimental data to realize automated and precise control of experimental processes, improving experimental efficiency and accuracy.
