2. 4GHz Wi-Fi and low-power Bluetooth (Bluetooth LE) dual-mode wireless communication with excellent RF performance. Uses high-quality relays supporting load up to 10A 250V AC or 10A 30V DC. Digital inputs with bidirectional optocoupler isolation, supporting both passive and active digital inputs; relays support联动 mode control for input signals. Onboard isolated RS485 interface enables easy expansion with various RS485 Modbus industrial modules or sensors. Onboard header pins allow connection to other devices. Onboard USB Type-C interface supports power supply and firmware download/debugging, convenient for development. Onboard terminal block power input supports wide voltage range from 7V to 36V, suitable for industrial power applications. Onboard RTC clock chip supports scheduled tasks. Onboard W5500 Ethernet chip provides 10/100Mbps network connectivity via SPI interface. PoE Ethernet version supports external PoE module for Power over Ethernet functionality (compliant with IEEE 802.3af standard). Onboard optocoupler isolation prevents interference from high-voltage circuits connected to relays affecting the control chip. Onboard digital isolation prevents external signal interference to the control chip. Integrated onboard power isolation provides stable isolated voltage; no additional power supply required at the isolated side
3. Built-in Micro SD card slot for external SD card storage of images or files. Onboard buzzer, RGB LED, power, and RS485 transmit/receive indicator lights to easily monitor device operation status. Rail-mounted ABS protective housing for convenient installation and safer operation
