Signal relays are components that allow large current and contact voltage control in electronics, particularly in telecommunication system designs. The type of relay we are discussing here is the 6-1393817-4 signal relay, which is a double-pole, single throw (DPST) type of relay that offers current capability of up to 2 amps. This type of signal relay has a wide range of applications, including use in power supplies, telecommunications equipment, and automobiles.

Application

The 6-1393817-4 signal relay finds use in many different applications where current control and contact voltage control is desired. In power supplies, the relay can be used for current isolation, filtering, and voltage sensing. In telecommunications equipment it can be used for switching voice communications and other signals between two points. Similarly, the relay can be used in automotive applications for switching audio, video, and other signals.

Working Principle

The 6-1393817-4 signal relay works in accordance with the basic principle of electromechanical relays. It has two electrical contacts, a coil, and a body that serves as an armature or switch mechanism. When the coil is energized, current is passed through the contacts, and the armature is drawn up, making an electrical connection. When the current is stopped, the armature releases the electrical connection and returns to its rest position.

Structure

The 6-1393817-4 signal relay is composed of several individual components, which work together to provide the function of the relay. It includes a coil, an armature, return springs, and contacts. The coil is a coil of insulated copper wire that produces an electromagnetic field when energized. This field then interacts with the armature in order to drive it up or down, depending on the direction of the current flow. The armature is composed of a flat metal disc attached to an insulated frame with two movable contact points. The return springs are located below the armature and ensure that the armature returns to its rest position when the current is stopped. Finally, the contacts are a pair of solid metal contacts, or poles, located on the armature that provide the contact voltage when the armature is energized.

Advantages

The 6-1393817-4 signal relay offers several advantages over traditional relays. First, it is capable of handling up to 2 amps of current, allowing for the switching of larger electronic loads. Additionally, the contacts are insulated from the coil, eliminating the risk of arcing and reducing contact wear. Finally, the armature is designed to return to its resting position automatically, eliminating the need for manual resetting.

Conclusion

The 6-1393817-4 signal relay is an excellent choice for applications that require current control and contact voltage control. It is capable of handling up to 2 amps of current, and its design features make it more reliable and durable than traditional relays. Additionally, its use in power supplies, telecommunications equipment, and automotive applications demonstrates its versatility to meet a wide range of applications.
