Frequently Asked Questions
What load can this relay module handle?
The onboard relay is rated for 10 A at 250 VAC or 10 A at 30 VDC. It’s suitable for controlling standard household appliances, small motors, and lighting circuits within these limits.
How do I pair the module with my phone?
After powering the module at 5 VDC, enable Bluetooth on your smartphone and scan for SPP devices. Select the relay module’s name, enter the default PIN (“1234” or “0000” if prompted), and use any Bluetooth terminal or compatible app to issue on/off commands.
Will it work near high-voltage equipment?
Yes. The built-in optocoupler isolation separates the relay’s high-voltage side from its control circuitry, reducing electromagnetic interference and ensuring stable operation even in electrically noisy environments.
