Power interface control installation for e.g. electric oven, has processing circuit comparing sensor signals to preset conditions and controlling switches according to preset control conditions stored in memory

摘要

The installation has a supply terminal associated to power units. A processing circuit (CT) is coupled to sensors to receive intensity signals, to a controlled switch to act on their start/stop function and to an input station (CE) to receive instructions of functioning of the power units. The circuit compares the sensor signals to preset conditions and controls the switches according to preset control conditions stored in a memory.
