5V 12V 4 Channel Relay Module

Input and output wiring and function description:
Output section: NC (normally closed) COM (common foot) N0 (normally open)
Load 220V 10A is recommended to be below 220V 6A
1. Just a switch is turned off and off without any voltage output.
2. The relay can only be controlled to open and close by 485 communication.
3. By default, NC COM is turned on. When 485 sends an open command, NC and COM are disconnected, and NO and COM are connected. on the contrary.
Input section: IN1 is connected to a switch or voltage signal (3V – 30V),
1. The status of the switch can only be read by the computer. The relay cannot be controlled. If necessary, the relay can be controlled to communicate with the store.
2. IN1 switch (no voltage signal): IN1 is connected to VCC computer to get 1 otherwise 0
Hardware resources:
1. RS485 communication interface
2. TTL communication interface
3. 1 input
4. 1 output
5. A user LED indicator
6. A STM32F030F4 microcontroller
7.1 relay status indicator LED lights
8. Power terminal interface (12V power supply)
Modbus RTU instruction
Baud rate: 9600 8 NONE 1
Hexadecimal transmission
Hexadecimal reception
Steps:
1. Software set communication baud rate
2. Set the address (device address used for communication, the default address is 01)
