Power module and interface module for a heating management and/or control system and modular system for heating management and/or control system

摘要

A housing has first and second communication interfaces, first and second voltage supply interfaces for voltage supply of the power module, power outputs, each connected to a heating element, and a power input electrically attached to a voltage supply for the heating elements. Enclosed by the housing is a power distribution device electrically connected on the input side to the power input and electrically connected on the output side via branches to the power outputs to supply these with electrical current. A switch element is provided in each branch. Switching states of the switch elements are controlled based on heating power reference values of the heating elements. Reference values are received via the first communication interface, with those intended for the power module being used to control the switch elements and those not intended for the power module being forwarded to the second communication interface.
