Title:
監視回路
Document Type and Number:
Japanese Patent JP4176185
Kind Code:
B2
Abstract:
A monitoring circuit which allows for the complete monitoring, at short intervals, of several signal inputs and consequently of signal outputs without having to take into account external interference, like for instance the execution time in the case of light barriers, is obtained in that the signal inputs are connected through two capacitors to at least one relay, in that the signal inputs apply a potential to the capacitors while oscillating and in that the capacitors discharge into the relays while oscillating.
