myDatalogC3e 3mA/6Rel

Output extension myDatalogC3e 3mA/6Rel

The extension module myDatalogC3e 3mA/6Rel is used for signal output of 3 mutually isolated mA (0/4…20 mA) outputs.
Furthermore, it offers 2 groups with a common root with 3 relays each. It is an output extension for devices of the myDatalogC3xx family .

Product features

  • 6x relay outputs for direct switching of loads

Product configurator

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.
