25Hz long track circuit is the longest track circuit in our country today. Its transmitted end uses the 25Hz Ferro-magnetic frequency divider, which was introduced in the Vol.8 No.2 of this magazine. Its received end uses the electronic relay which is introduced here. The features of this electronic relay are: very high the release factor, most sensitive, low power consumed, worked stably and reliably. The circuit is simple, produced and regulated easily etc. It consists of six parts: the track transformer, 25Hz band pass filter, potential gate flip-flop, frequency selective amplifier, executing circuit and the rectified power source. This paper recommands briefly the working principles and the specifications of these six parts.
