Frequently Asked Questions
Can I access the relay module over the internet?
This module works within a local area network by default. To control it from outside, configure your router for port forwarding or use a VPN to connect securely to your LAN.
What loads can I switch with these relays?
Each channel handles up to 250 VAC at 10 A or 30 VDC at 10 A. Exceeding these ratings may damage the relay contacts and reduce lifespan.
Is any additional software needed to use the module?
No additional drivers are required. You can control the relays using standard AT commands via any USB-TTL adapter at 9600 baud or through the provided smartphone app.
