Velleman VM201 Ethernet Relay Card

Velleman VM201: Ethernet Relay Card

Velleman VM201

The Velleman VM201 Ethernet Relay Card (Velleman Module No Soldering Required)

With the Velleman VM201 you can control 8 relays and check the status of 1 input from anywhere in the world. Sitting in your favorite chair but want to turn a light or fan on from across the room? With the free app for IOS and Android, you can do it with your phone or tablet and using the Web interface you can do it from your computer. Plug the Velleman VM201 into your wireless router (standard RJ45 connector) and connect the load i.e. lights, fans and other electrical devices. The ratings for each relay are 12 Amps @ 30 volts DC or 16 Amps @ 230 volts AC. You can even set timers to automatically turn them on or off. Connect a magnetic switch to your door and check to see if it’s open. Don’t worry about setting the clock, the ethernet relay card can set the clock on its own through the SNTP (Simple Network Time Protocol). Receive an email report at power up or when the input status has changed. You can change the names of the input (front door, back door) and the outputs (lamp, fan, radio). The TCP port can be changed as needed. To control the VM201 outside of your house or business TCP/IP and port forwarding on your router is required.

The Velleman VM201 does require a power supply 12 volts AC at 500mA.
