Solid Sky is a versatile wireless device that is easy to install and set up and also has a wide radio range. Solid-Sky has a durable battery, but you can also connect an external power supply to it. With the help of Solid-Sky, you can occasionally supply power to e.g. two two-wire 4-20 mA transmitters, even if you only use the Solid-Sky transmitter with batteries.

The Solid-Sky-2Pro-DIO-RS485 version has two mA or V inputs and three digital inputs. It also has an RS485 serial interface, so you can integrate Modbus RTU Slave devices wirelessly with the Solid-Sky-2Pro-DIO-RS485. If you need fewer inputs, check out our Solid-Sky-2Pro.
