Power relays providing currents of over 2 amps have become increasingly popular in various applications due to their high switching capacities and increased durability. One such example is the AJD55024, a device that offers numerous advantages over its peers, and is versatile enough to be used in many scenarios. This article will discuss the AJD55024’s application field and working principle.

The AJD55024 is designed for a wide range of applications, ranging from load and motor control to current measurement. In terms of load control, the device is equipped with a heavy-duty contact rating of 25A @ 250VAC, allowing it to withstand severe operating conditions and provide reliable operation. It is also suitable for motor control applications, as it is equipped with a beaux rating of 10A (@250VAC) and can withstand a 10amp motor. Additionally, its integration of an adjustable time delay makes the device an ideal choice for industrial timers.

The AJD55024 is especially advantageous in current measurement applications due to its adjustable output power. This allows the user to set the relay’s output within a range of between 4-20mA. This adjustable output power, as well as integrated protections for over-currents, short-circuits, and other conditions, make the AJD55024 suitable for any current measurement task.

The AJD55024 also features a wide range of characteristics and configurations. For example, it is equipped with a wide operating temperature range of -40°C to +85°C, making it suitable for harsh environments, and it is rated for a dielectric strength of 1000VAC at 50/60Hz for 1 minute. Additionally, its dimensions are only 11.07 mm x 6.4 mm x 22 mm, providing a compact size for integration into a range of scenarios.

The working principle of the AJD55024 involves the simple use of electromechanical switching. When energized, a magnetic field is created by an electromagnet, which then attracts an armature and changes the position of its contact points. This enables or disables the flow of current depending on the state of the armature. When the current is no longer applied, the armature returns to its original position, thus re-enabling the operation.

In conclusion, the AJD55024 is a versatile power relay that can be used in a wide range of applications, such as load and motor control, and current measurement. It has a variety of features, such as adjustable output power and integrated protections, and is characterized by its small package size and wide operating temperature range. And finally, its operation is based on the simple principle of electromechanical switching.
