Main features of the product:
1. The relay is a heavy-duty DC electromagnetic relay, which uses the principle of "constant gravity" to force the closing contact to disconnect when the coil is powered off.
2. Using silver silver cadmium oxide contacts, it has strong anti adhesion and low contact resistance.
3. The magnetic circuit adopts electromagnetic pure iron material with small residual magnetism, and a stopper is installed at the closure between the armature and the iron core to ensure a small air gap in the magnetic circuit, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure the reliable dropping of the relay.
4. The front coil of the relay is a short-circuit coil enclosed by a diode, without a rectifier unit. The AC power supply is directly connected to the coil and has a certain lightning protection function.
5. The relay contact system consists of ordinary contacts, with four sets of common contacts for dynamic connection and dynamic disconnection conversion.
6. Relays should be used in conjunction with isolation transformers to adjust the system current to ensure reliable operation and release of the relay, and to ensure that the lamp terminal voltage meets the specified adjustment range.
Product dimensions:
Relay: 165 mm x 49 mm x 163 mm (length x width x height)
Socket: 157 mm x 48 mm x 22 mm (length x width x height)

Product installation method:
The relay socket is installed on the combination frame (cabinet) with bolts, and the relay is horizontally inserted into the socket and clamped with a hanging spring.

Relay identification sales numbers 13 and 53.

The JXW-25A microelectronic phase sensitive track circuit receiver is in the form of a safety relay, called the JXW-25A type. The terminal allocation is shown in Figure 3, and each relay combination can install 4 sets of track circuit receivers (including protective boxes, selenium stacks, and capacitors). The external wiring of the combination is shown in Figure 8.

The JXW-25B microelectronic phase sensitive track circuit receiver is a dual set product of the JXW-25A model. As long as one of the two sets of equipment can work normally, it can ensure the normal operation of the system and further improve its reliability; If one of the sets malfunctions, it can promptly sound an alarm and notify maintenance personnel for repair. Moreover, repairing a single set does not affect the system's use, greatly facilitating on-site maintenance.

The JXW-25C microelectronic phase sensitive track circuit receiver is a dual set product with the same structure as a single set. Its function and function are the same as the B-type dual set receiver. The terminal wiring diagram is shown in Figure 5.

The JXW-25B microelectronic phase sensitive track circuit receiver is divided into a receiving transformer box and a microelectronic receiver box, both of which are installed inside a safety relay cover. The terminal wiring diagram of the JXW-25B microelectronic receiver box is shown in Figure 4. Each receiving transformer box is equipped with two track receiving transformers, and the terminal wiring diagram is shown in Figure 6.
