The JXW25 microelectronic phase sensitive track circuit receiver is based on a microprocessor and uses digital processing technology to analyze track circuit information, detect useful information, remove interference, and complete the 25Hz phase sensitive track circuit receiving function in the electrified section.

The microelectronic phase sensitive track circuit receiver is divided into single set equipment (Type A) and double set equipment (Type B, Type C) according to usage needs. The equipment is installed inside a safety type relay cover and uses relay sockets. The B-type double set includes an electronic receiver, a receiving transformer box, and an alarm box. The structure of the C-type dual set equipment is consistent with that of a single set, while its function is the same as that of the B-type dual set, making it easy to replace existing single set equipment for updates and upgrades.

1. The return coefficient of the microelectronic phase sensitive orbit receiver is greater than 90%.

2. The ideal phase angle between the track input signal of JXW25 microelectronic phase sensitive receiver and the local power supply is -90 °;

3. The strain time of the microelectronic phase sensitive track circuit receiver is less than 0.5S.

4. The microelectronic phase sensitive receiver adopts multiple software and hardware protection measures to ensure compliance with railway signal fault safety requirements.

5. Microelectronic phase sensitive receivers have good lightning impulse resistance.

6. The equipment power supply adopts DC 24V ± 15%.

7. When the ambient temperature is between -25 ℃ and+60 ℃, the equipment operates reliably.
