A Modbus digital display is a display terminal that communicates with devices via the RS485 bus and uses the Modbus RTU protocol to transmit data. It displays industrial parameters (such as voltage, pressure, and temperature) in digital form.
Features
Communication Protocol: Supports Modbus RTU, and some products also support ASCII, facilitating seamless integration with controllers such as PLCs and microcontrollers.
Display Function: Displays numbers, characters, and symbols, and supports brightness adjustment, blinking, and error handling.
Environmental Adaptability: Providing industrial-grade quality, it operates stably across a wide temperature range and in harsh environments.
Interference Resistance: Using RS485 communication, it offers strong interference resistance, making it suitable for long-distance transmission and complex industrial sites.
Typical Application Scenarios
1. Industrial Automation
Production Line Monitoring: Real-time display of production data such as temperature, pressure, flow, and output helps operators understand production status and adjust parameters to ensure normal operation.
Equipment Status Indicator: Displays equipment operating status, fault codes, and other information, enabling quick problem location and resolution, reducing equipment downtime.
2. Energy and Power Systems
Power Monitoring: Displays power parameters such as voltage, current, power, and energy in substations and distribution rooms, enabling real-time monitoring of power system operation and prompt detection and resolution of abnormalities.
New Energy Equipment: Displays key information such as power generation, power factor, and battery charge for photovoltaic inverters and wind turbine systems, facilitating monitoring and management of new energy equipment.
3. Building Automation
Elevator Monitoring: Displays elevator operating floors, direction, and fault information, improving elevator safety and management efficiency.
Environmental Monitoring: Connects to temperature, humidity, and air quality sensors to display real-time indoor environmental data, providing decision-making support for building automation systems.
4. Healthcare
Medical equipment monitoring: Monitors, such as monitors and ventilators, display patient physiological parameters and device operating status, providing critical medical information to healthcare professionals.
With their powerful communication capabilities, flexible display capabilities, and excellent environmental adaptability, Modbus digital tubes play an important role in numerous fields. They provide reliable data display and monitoring for industrial automation, energy management, building control, and other applications, improving system efficiency and reliability.
