It controls the absorption and release of the 2-way relay through Ethernet network and Internet, and can extend the relay module to 8-way output from the pin laying outside. The module supports TCP, UDP and cloud remote control. The instructions are simple and easy to understand. The 1-65535 second delay can be specified in the instructions. The cloud remote control public service platform is free to use permanently, the control is protected by the local password, the operation is safe and reliable. Module with VB, computer program and source code, to help you easily achieve computer remote control. TCP and cloud remote control can query the status of all relays. In addition, after each instruction is processed, the module will return the current status of all relays. UDP mode has no status query or other return, the code is extremely simple, easy to embed in various applications.
Fully support secondary development, open TCP, UDP control protocol, cloud remote secondary development package provides SOAP Web Service API interface and RESTful Web Service API interface.
