Frequently asked questions
What supply voltage does the receiver need?
The receiver module is rated for DC 12 V, so power it from a 12 V DC supply rather than from mains.
Can it switch mains AC appliances?
The relay contacts are rated 5A at 250VAC, so it can switch AC loads within that rating. Check the load current and use proper insulation and an enclosure when switching mains voltage.
