Modbus RTU Relay 1 Channel Network Relay Module Single way Ethernet LAN Controller Power Supply Accessories

Features:

The single-way Modbus network relay module is equipped with a mature and stable 32-bit MCU and W5500 full hardware TCP/IP protocol stack network chip.

MCU debugging interface is reserved to support secondary development.

The standard MODBUSRTU format communication protocol can be used to control one relay output in a local area network, which can be used for power control under wired network.

With input anti-reverse connection protection.

With diode diarrhea protection, short response time;

7. MCU UART debug interface: GND, RXD, TXD: TTL level UART

Communication interface, GND, RXD, TXD are connected to the external console GND, TXD, RXD, support the connection of 3.3V/5V external TTL serial port, default for serial view device IP address and port number, baud rate 115200;

8.1 way relay switch signal output:

NC: Normally closed, shorted to COM before the relay is closed, suspended after closed;

COM: Common terminal;

NO:Normally open terminal, the relay is overhung before suction, and shorted to COM after suction.
