Signal Relays, Up to 2 Amps

Signal relays, such as the 8-1393817-2, are electromechanical devices used to control an electrical circuit, such as a fan, air conditioning unit, pump, motor, or other electrical circuit, by closing or opening a contact. The 8-1393817-2 is a signal relay capable of up to 2 amps of power, and is ideal for applications where the relay needs to be triggered at low current or low voltage.

Application Field

Signal relays such as the 8-1393817-2 have a wide range of applications. Due to its low power requirements, it is often used in digital circuit applications where low current or low voltage is required. It is perfect for protecting delicate circuitry from power surges and spikes as well as low power sources such as batteries and solar cells. It can also be used in applications that require sensing or monitoring low level current signals such as temperature, pressure, current or voltage levels.

The 8-1393817-2 is also suitable for switching applications in which reliable operation of an electrical circuit is required when triggered by a low current or low voltage. Its low power requirements make it perfect for controlling low power devices such as small motors, fans, pumps, and other low power machinery.

Working Principle

Signal relays, such as the 8-1393817-2, operate by the principle of electromagnetism. When a small electrical current is passed through the coil of the relay, it creates a magnetic field which attracts a plunger attached to a metal bar which in turn closes or opens the switch mechanism holding the contacts of the relay closed or open. When the current is removed, the magnetic field dissipates and the switch mechanism reverts to its original state, opening or closing the contacts.

The 8-1393817-2 is capable of switching up to 2 amps and has a contact width of 0.5mm. It is rated for up to 24 VDC and is typically used for low power control or sensing applications. While designed for low power switching, it is also capable of switching higher current levels if the contact gap is adjusted for correct current rating.

Conclusion

Signal relays, such as the 8-1393817-2, are often used in low current applications due to their low power requirements. It can be used in applications such as digital circuit protection, low power device control, and monitoring low level current signals such as temperature, pressure, current or voltage levels. It is also capable of switching higher current levels if the contact gap is adjusted for correct current rating.
