ELECTRICAL OR ELECTRONIC SAFETY MODULE

摘要

The invention relates to a time-controlled crowbar (11) which is designed such that it monitors the switched-on period (t) of the at least one downstream electronic component (12) and the period length (T) of the clocking and hence the supply of power such that a maximum permissible surface temperature - prescribed in the area at risk of explosion - for the at least one downstream component (12) is not exceeded.
