Abstract
Завесата намира приложение в промишленото оборудване. Тя е с повишена функционална надеждност. Съдържа два фотоелемента, всеки от които оптически е свързан поне с един светлинен излъчвател, задаващ генератор, включен към входовете на излъчвателите чрез блок за разпределение на импулсите, логически блок за контролиране равнозначността на сигналите на изходите на фотоелементите и свързания с него сигнализатор. Завесата включва и схема за блокиране на сигнали за включване на сигнализатора, чийто вход е съединен с изхода на логическия блок за контролиране равнозначността на изходите на фотоелементите, а изходът и е включен към входа на сигнализатора. 6 претенции, 5 фигуриThe curtain is used in industrial equipment. It has increased functional reliability. It contains two photocells, each of which is optically connected to at least one light emitter, setting a generator connected to the inputs of the emitters through a pulse distribution block, a logic block for controlling the equivalence of the signals at the outputs of the photocells and the signalizer connected to it. The curtain also includes a circuit for blocking signals for turning on the annunciator, the input of which is connected to the output of the logic block for controlling the equivalence of the outputs of the photocells, and the output of which is connected to the input of the annunciator. 6 claims, 5 figures
