Product Description
Product Overview
The TW-NBIoT communication module enables independent installation of energy meters with unified electrical interfaces, eliminating the need for secondary development of electric energy meters. This edge computing-based solution supports both single and three-phase smart watt hour meters.
Key Features
- Built-in MCU with edge computing capability for local data processing
- Automatic binding with smart meter communication addresses upon power-on
- Configurable upload cycles and task lists for optimized data transmission
- Priority handling of platform gateway instruction frames with real-time bidirectional transmission
- Standard State Grid communication interface and module box design for direct replacement (hot plug compatible)
- Non-volatile parameter storage with automatic recovery after power restoration
- Independent power conversion circuit supporting DC12V power supply
