This new DIN rail WLAN relay card VM208 combines the strength of four robust  relays that you can control via smartphone. In other words: 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. Tip: 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. Expandable, add 8 more relay output by adding a VM208EX   *Port forwarding required.
