Beschreibung
Zusammenfassung:	FIELD: electrical engineering, warning, centralizing, and interlocking devices for railway transport. ^ SUBSTANCE: proposed relay has optocouplers provided with input diodes and using rectifier bridge circuit arrangement. There are AC power supply and DC relay connected to AC input and DC output of mentioned rectifier bridge, respectively. AC control voltage source is also provided. Input diodes of each pair of optocouplers inserted in respective arms of rectifier bridge are connected to AC control voltage cumulatively with respect to rectified -voltage polarity and differentially relative to input diodes of other pair of optocouplers. ^ EFFECT: provision for protecting relay against operation under impact of alternating-current interference whose voltage frequency and phase are other than those of useful signal. ^ 1 cl, 1 dwg
