1P18U1/39

Accessory: 1P18U1/39 Application Field and Working Principle

The 1P18U1/39 is a type of accessory, consisting of two signal relays connected in parallel. It provides an efficient process for operating signal systems with a single signal.

Application Field

The 1P18U1/39 accessory is mainly used in traffic control systems, which enables signal systems to display various patterns with a single signal. This can be used to control intersections, curves, gradients and other areas. Besides, the device can also be applied to railway signal systems, train crossing signals, and other related applications.

Working Principle

The 1P18U1/39 accessory consists of two signal relays each with a single-phase solenoid switch, which is temporarily energized using a relay coil. The 1P18U1/39 accessory has two relay output contacts, which can be used as a switch. The system works by connecting the two wires from the relay contacts together. When the relay contact is energized, the signal is sent to the other side of the system, which then energizes the solenoid switch to turn the signals on or off.

Advantages

The main advantage of the 1P18U1/39 accessory is that it provides an efficient process for operating signal systems with a single signal, which is much more efficient than traditional manual methods. Furthermore, it is simple to install, and can be operated reliably.

Conclusion

In conclusion, the 1P18U1/39 accessory is a useful device which can be used in various signal systems and traffic control applications. It is simple to install, and provides reliable and efficient operation.
