(U _out ≠0) . In this case, the output voltage U_out through the amp it will turn on relay P, which, with a normally open contact, will turn on optical and audio alarms.

Conclusion
The static characteristics of optoelectronic discrete converters are determined on the basis of a joint consideration of the designs of converters with hollow and fiber light guides and the corresponding measuring circuit with a radiation receiver. It is shown that dividing and bridge measuring circuits are primarily used in optoelectronic discrete displacement transducers.
The static characteristics of relay optoelectronic discrete converters with concentrated radiation sources based on hollow and fiber light guides are obtained for longitudinal and transverse movements of the external modulating body.
The dynamic characteristics of optoelectronic discrete displacement transducers can be described by a first-order aperiodic link, and the curves of changes in the shape of the output signals of discrete transducers significantly depend on the speed of movement of the controlled volume, liquids, piece goods and materials.
