This product uses 470MHz LoRa wireless communication technology platform, and the communication protocol uses the Internet of Things micro power wireless network communication protocol of the State Grid power transmission and transformation equipment to achieve dual-way communication. The load status can be viewed in real time through the monitoring terminal, and remote control can be carried out. It has the characteristics of green environmental protection, maintenance free, complete electrical isolation, convenient installation, strong anti-interference ability, reliable operation, compact size, etc., and can well solve the load control problems of motors. The collected data is transmitted to the monitoring terminal through RF communication in real time to achieve uninterrupted and accurate measurement and control.

1. Main functions
The product has an operation indicator light and a power switch. After the product is connected, press the power switch, and the operation indicator light flashes slowly. After the equipment is successfully linked to the sink node, the operation indicator light is always on. At this time, the equipment operates normally. The load operation status can be viewed through the supporting cloud service terminal, and remote control can be performed. Each product has a unique equipment ID, which needs to be recorded during use.
2. Definition of connecting terminal
L N: Connected to 220VAC AC
A B: Connected to RS485 communication line
