This new DIN rail WLAN relay card VM208 combines the strength of four robust relays that you can control via smartphone. This device enables you to remotely control any appliance in your electrical cabinet from anywhere in the world.

For your convenience, we also added both wired (RJ45 socket) and wireless connections (SMA plug). There is one digital input that lets you monitor the state of any device and there are two additional transistor outputs that allow you to control 6 devices in total. To top things off, we designed a compact DIN rail case that perfectly fits this versatile relay card.

Once you’ve installed your relay card and connected it to your preferred appliance(s), you can install the app and scan your network to connect your app to your relay card.

Multiple relay cards can be connected to your app. To make a successful connection, you will simply need to select your relay card on the list and enter your credentials. After that, you will get an overview of all your relays or channels and you will be able to give them individual names. Each channel can now be controlled: you can turn it on or off, install a timer or pulse, schedule, and even send out an email notifications at specific events.
