Frequently asked questions
What supply voltage does the module need?
The module is rated for 12 V DC, as stated in the listing. Check the relay contact rating printed on the board before switching any load.
Can it switch mains-powered appliances directly?
Only if the relay contact rating covers the load current and voltage. Mains wiring must be properly insulated and enclosed; if unsure, use a qualified electrician.
