Feature:1. CHIP AND SPEED: Network relay module carries mature and stable 32bit MCU STM32F103C6T6 chip, W5500 all hardware D CP or P protocol stack Ethernet chip, supporting 10/100M bps rate2. TECHNICAL PARAMETERS: Network relay module supports standard RTU protocol. The flute serves as the TCP Server and supports the IP address DHCP function. The port number is 5000. You can view the module IP address through the serial port. The baud rate of UART communication is 1152003. OUTPUT SIGNAL: The relay switch signal supports manual, flashover closure, flashover mode. The delay base of flashover closure or flashover is 0.1S, and the maximum flashover closure or flashover time can be set as 0xFFFFx0.15=6553.5Ss4. SAVE AND READ: The device address ranges from 1 to 255, the default address is 255, which can be saved after power failure. The relay status and device address can be read using software or instructions5. PROTECTION FUNCTION: Onboard 1 channel 5V 10A, AC 10A, 3OV DC relay, can be continuously drawn 100,000 times, with diode pollution current protection, response time is short6. SUPPORTED FUNCTIONS: Onboard power supply and relay switch indicator light, MCU reset button, reserved UART serial port and SWD program write port, support secondary development; The power supply voltage is DC728V and supports 5.08mm terminal power supply with input non reverse connection protectionSpecification:Item Type: Network Relay ModuleMaterial: PCB1. Main Control MCU: STM32F103C6T62. Network Chip: W5500 all hardware TCP or IP protocol stack Ethernet chip3. Network Interface: 10M 100Mbps HR911105A network transformer4. 5.08mm Terminal Power Supply Port: DC7-28V power input, GND is negative5. MCU Reset Button: Short press reset6. MCU SWD Debugging Interface: Secondary development burning7. MCU UART Debugging Interface: GND, RXD, TXD: TTL level UART communication interfaces, GND, RXD, and TXD are connected to the GND, TXD, and RXD of the external control end respectively. The 3.3V or 5V external TTL serial port is supported. By default, used to view the IP address and port number of the device through the serial port with a baud rate of 115200.8. 1 Relay Switch Signal Output: NC: Normally closed end, short connect with COM before relay closing, suspended after closingCOM: Public terminalNO: Normal start, the relay is suspended before closing, and short connected with COM after closing.Package List:1 x Relay Module1 x 8P Pin Header
