Relay Module 2 Way 12V Input Relays Switch Board Shields for Circuit Communicationn

Item Type: Relay Module
Material: Copper Clad Laminate
Input and Output Wiring and Function Description:
Output Part: NC (Normally Closed) COM (Common Pin) NO (Normally Open)
Load: 220V 10A (Recommended Below 220V 6A)
1 is just the closing and opening of a switch, without any voltage output.
2 Only through 485 communication can send commands to control the opening and closing of the relay.
3 By default, NC COM is connected. When 485 sends the opening command, NC and COM are disconnected, and NO is connected to COM.
Input Part: IN1 Connects to Switch or Voltage Signal (3V-30V)
1. The status of the switch can only be read through the computer, and the relay cannot be controlled.
2. IN1 is connected to the switch (no voltage signal): IN connected to VCC is 1, not connected to 0

How to Use:
Steps:
1. The software sets the communication baud rate
2. Set the address (the device address used for communication, the default address is 01)
Note: Only connect one device, otherwise the address will be set.
Set the address as: 01
00 10 00 00 00 01 02 00 01 6A 00 　 modify to 01
Set the address as: 02
00 10 00 00 00 01 02 00 02 2A 01 is changed to 02
Set the address as: 03
00 10 00 00 00 01 02 00 03 EB C1 is changed to 03
Read address
00 03 00 00 00 01 85 db
return:
00 03 02 00 01 44 44　01 is the address
