Additional power to the ComBricks backplane in case the Head Station loses power

The Anybus 6A Power module provides additional power to the ComBricks backplane in case the Head Station is no longer able to power all inserted modules.

Multiple power modules can work in parallel and their currents are accumulative with a maximum combined current of 12A.

The power modules can also be used as a redundant power source for the backplane. Diagnostics of the power modules are available on the web server.
