myDatalogC3e 12UI/2Rel

Input extension myDatalogC3e 12UI/2Rel

The myDatalogC3e extension module is used for signal acquisition from 12 universal inputs and for controlling 2 actuators by means of potential-free relay contacts. The extension module has a co-processor. The bus coupling to the myDatalogC3 is done via CAN interface.

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.
