Description :

The LPN Modbus Bridge is very general device, which allows the integration of any sensor, actor or even an SPS control which has the Modbus Interface to the LoRaWAN network. The data were transmitted to any LoRaWAN network, for example in Switzerland through the public network from Swisscom. The bullet point is that you can integrate this device in your application directly. Also it’s possible that we provide you an application which fits for your needs.

The compact Size, the outdoor housing and the externally antenna are perfect for outdoor use. The device mounted outdoor gives extra spare if you have bad network coverage. The Input power with 10 to 30 VDC needs to come externally, therefore you don’t have to think about battery lifetime. After the installation, there is an easy procedure with a pushbutton inside the device. So you can check directly if you have coverage or not after the installation of the device.

The status LED’s shows the device status and flashes if a new message is sent or received. A core feature of the LoRa Modbus Bridge is that the device has a USB connection inside for very easy setup and integration into your LoRaWAN network. Of course, you can use the LoRa Modbus Bridge device with our comtac cloud. We can also provide our cloud solution with your company logo or we install the software on your server.
