The extension is built into the housing and adds an electrically isolated RS485 interface to the myDatalogEASY IoT. The extension is fed from the RS232 port supply, which can be switched via device logic. In addition to the isolated bus, a galvanically isolated 5V/50mA sensor supply is available at the 4-pin connector.

With the help of the runtime calculator, you can estimate the autonomous runtime of the application as well as the costs incurred. The actual costs and energy consumption depend on the measurement conditions, such as the reception quality and ambient temperature. Detailed information on the tariffs can be found here.
