Introduction:

The NB-IoT Collector (Model: JRH-WNOA/B) is an advanced data collection device designed for battery-powered meter reading equipment, particularly suited for scattered, hard-to-access large meters (e.g., water meters) in remote or decentralized installations to obtain electricity. It ensures reliable, low-power, and long-distance data transmission via NB-IoT technology, making it ideal for smart utility management.
It uses a high-performance 8-bit ultra-low power MCU hardware platform to regularly collect and store water meter data, and can exchange data with the master station through NB-IoT. The downlink interface TTL communicates with the meter, which is suitable for single-point data upload of decentralized installed meters.

Key Features

1. Ultra-Low Power Consumption

   • Average current as low as 5μA in standby mode, significantly extending battery life.

   • High-efficiency power management for prolonged operation in energy-constrained environments.

2. Robust Communication Capabilities

   • Uplink: NB-IoT (Supports Band 5 or Band 8) for secure, wide-area data transmission to the master station.

   • Downlink: 1× TTL interface for seamless communication with meters (compatible with RS-485/M-BUS protocols).

3. High Reliability & Durability

   • MTBF ≥ 100,000 hours, ensuring long-term stability.

   • 600W lightning surge protection per RS-485 line, safeguarding against electrical disturbances.

   • Industrial-grade design: Operates in -25℃~50℃ (extended range: -30℃~65℃) and humidity up to 95% RH.

4. Flexible Deployment

   • Compact dimensions (140mm×97mm×24mm) for easy installation in confined spaces.

   • Supports four output channels, adaptable to single-point or multi-meter configurations.

5. Standardized Protocol Support

   • Complies with CJ/T 188-2004 protocol, ensuring compatibility with most meter systems.
