The DI810 is a digital input module manufactured by ABB, belonging to the S800 I/O series. Here is a detailed introduction:
It is mainly used to collect digital signals from external devices, such as switch signals and sensor signals, and convert them into signals that can be processed by PLC (Programmable Logic Controller), thereby realizing monitoring and control of industrial processes.
- Input Voltage: 24V DC
- Input Current: 6mA
- Number of Channels: 16 digital input channels, divided into two groups with 8 channels each
- Isolation Method: Electrical isolation
- Operating Temperature Range: -20°C to +60°C
- Protection Class: IP20
- Dimensions: 102mm × 119mm × 45mm
- Weight: Approximately 0.2kg
- Response Time: Less than 1ms
- Modular Design: Facilitates installation and maintenance, allowing for easy integration into existing systems and simplifying troubleshooting.
- High Reliability: Adopts industrial-grade design with excellent anti-interference capability and stability, making it suitable for harsh industrial environments with electromagnetic interference or temperature fluctuations.
- Flexible Configuration: Supports multiple input types, such as dry contacts, wet contacts, normally open/normally closed contacts, etc. It also supports hot-swappable functionality, enabling module replacement or addition without shutting down the system, thus reducing downtime.
- High-Speed Response: Supports fast cycle times, ensuring timely collection and transmission of signals—critical for scenarios requiring real-time monitoring (e.g., emergency stop signals or high-speed production line statuses).
- Status Indication: Equipped with LED indicators to display channel statuses, allowing users to intuitively check the working condition of the module and quickly identify abnormal channels.
- Protocol Support: Compatible with the Modbus RTU protocol, facilitating communication with other devices in the industrial network and enhancing system interoperability.
Widely used in industrial automation, process control, power systems, and manufacturing industries. It can be used to collect various switch signals, limit switch signals, button signals, etc. Additionally, it is applicable for monitoring process variables such as liquid level, temperature, and pressure, as well as status monitoring of automated equipment like machine tools, assembly lines, and robots.
