Power relays have a wide range of applications across various industries and can be used to control long distance, high power appliances. ALZ21B4H is a type of power relay which is specially designed for use in medium-power applications, up to a maximum of 2 amps. It offers reliable and efficient power switching for applications that require a moderate amount of current. The ALZ21B4H relay is a single-pole, single-throw (SPST) switch with a single common or ground terminal and two other contacts - one normally open (NO) and the other normally closed (NC). The contact rated current rating of the ALZ21B4H is 2 amps, with a voltage rating of 110 VAC and a maximum power rating of 220 W.

The ALZ21B4H relay is built from premium materials that make it highly reliable and durable. It has a strong silver-nickel contact form which gives it excellent performance in terms of resistance to wear and corrosion. The contact material used is also designed to provide maximum current-carrying capacity and improved contact bounce times. The contact biasing system of the ALZ21B4H is designed to prevent contact welding and ensures smooth operation in applications with frequent cycling.

The ALZ21B4H is easy to install and operate. It is fully sealed to prevent the entry of moisture or dust and is suitable for both indoor and outdoor applications. It is also designed for direct mounting onto a printed circuit board, making it ideal for industrial and commercial use. The ALZ21B4H relay has an operational temperature range of -40 to +85C and the coil is rated at 5VA.

The ALZ21B4H relay is designed with a wide range of power applications in mind. It can be used in switching motors, lighting systems, home appliances, and various types of industrial equipment. It is also suitable for use in audio systems, as it can reliably switch on and off amplifiers without creating noise. Other applications of the ALZ21B4H include audio systems, as it provides reliable switching without introducing noise.

The working principle of the ALZ21B4H is based on a simple magnetic field. When a current is applied to the coil, a magnetic field is generated, which causes the relay contacts to close. When the current is switched off, the magnetic field disappears and the contacts open again. The operation is fast and reliable, providing protection against sudden power fluctuations and short circuits in applications with heavy duty and infrequent switching operations.

The ALZ21B4H is an excellent choice for applications that require medium power relays. Its robust construction and high current capacity make it ideal for a wide range of power switching applications. It is reliable, efficient, and easy to install and operate, making it the perfect choice for controlling a range of long distance, high power appliances.
