Frequently Asked Questions
1. What is the maximum load each relay can handle?
Each relay is rated for AC 250 V at 10 A or DC 30 V at 10 A, making it suitable for switching lighting, motors, pumps and other heavy loads.
2. How can I change the Modbus address and baud rate?
The module supports AT-style commands over the RS485 interface. Send the predefined AT command for setting device ID (e.g., “AT+ID=03”) or baud rate (e.g., “AT+BAUD=9600”) and power-cycle to store the new configuration.
3. Can I interface this directly with an Arduino?
You need an RS485 transceiver or shield on the Arduino side. Connect the module’s A/B lines to the transceiver, power the board at 5 V, and use a Modbus RTU library to send commands to the relay module.
