T9AS1D22-18

Power relays are important devices which are used to control high-power electrical applications. They are used to switch circuits on or off and can be programmed for different applications. The T9AS1D22-18 is a power relay designed specifically for controlling circuits in safety critical applications of over 2 amps. This relay is designed with features that ensure safety and dependable performance.

T9AS1D22-18 Application Fields

The T9AS1D22-18 relay is used for controlling circuits in safety critical applications such as energy efficiency, power stability, overload protection and automatic machinery control. It is suitable for applications with AC circuits over 2 amps, such as industrial air conditioners, electrical heaters, high-power motors, clutches, solenoids and DC drives. It is also suitable for complex applications such as access control systems, remote automation, and power failure protection.

T9AS1D22-18 Working Principle

The T9AS1D22-18 relay consists of an integrated circuit (IC) and an actuator (coil) which, when energized, generate a magnetic field that closes the switch contacts. This generates a pulse or a series of pulses which are then transmitted to the control logic circuits that perform the desired functions in the application. The power relay will remain closed while the control logic circuit signals the actuator to open it. This removes the power from the controlled circuit and allows the installation to be reset or switched off.

The T9AS1D22-18 relay also has overload protection features that will open the contacts if there is an overload or short circuit on the controlled circuit. This protection feature is designed to prevent damage to the equipment due to excessive current. The power relay also has a built in protection feature that prevents the contacts from arcing. This feature prevents the contacts from sticking and improves the life of the relay.

Conclusion

The T9AS1D22-18 is a power relay that is designed specifically for safety critical applications over 2 amps. The relay consists of an integrated circuit (IC) and an actuator (coil) which, when energized, generate a magnetic field that closes the switch contacts. The power relay has overload protection features and a built in protection feature that prevents arcs from forming on the contact points. This power relay is suitable for applications such as energy efficiency, power stability, overload protection and automatic machinery control.
