Power Relays, Over 2 Amps

The 1617787-5 is a power relay designed for common applications requiring high current switching. Its maximum switching capacity is 2 Amps, and it operates with a switching voltage up to 250 VAC.

What Is A Power Relay?

A power relay is a device that is used to control the flow of electric current in a circuit. It is a mechanical switch that is activated by an external power source, often a signal from another circuit or control system. Power relays are used to control and operate motors, electrical switches, and other power circuits.

In the case of the 1617787-5, the operating power is supplied by an external AC power source. The relay will switch automatically when the power source is applied and remain closed until it is either manually switched off or loses its power source.

Application Field

The 1617787-5 has a broad range of applications. It can be used to control motors, ventilation fans, lighting fixtures, and other residential and commercial devices that require switching of either AC or DC power. It is also suitable for use in a variety of industrial, automotive, and medical applications.

This power relay is also suitable for applications that require both momentary and latching switching. Momentary switching works by momentarily applying the power supply, while latching switching works by maintaining the state of the relay until it is manually reset.

Working Principle

The 1617787-5 has an integrated circuit board with two terminals and a few additional components. The two terminals are connected to an AC power source, and the additional components handle the switching of the power.

When the power is applied to the terminals of the relay, the integrated circuit passes a current to open or close the mechanical contact to switch the power. This is known as the “load switching” feature. When the power is removed from the terminals, the integrated circuit is deactivated, and the relay returns to its original position.

The 1617787-5 maintains a level of safety since it is also equipped with a fail-safe feature, meaning that if the power is removed from the terminals, the relay will automatically switch off and remain in this state until the power is restored and then resumed its normal operation.

Conclusion

The 1617787-5 is a power relay that is suitable for a variety of applications requiring high current switching. It has an integrated circuit board with two terminals and additional components to handle the switching of the power. It is also equipped with a fail-safe feature that will keep it in the off position if the power is removed. This relay is designed to be used for applications such as controlling motors, ventilation fans, and lighting fixtures.
