Power Relays, Over 2 Amps

JS1A-B-12V relays are used when switching current levels over 2 amps. They are primarily used in distributed control systems and process control applications. They are microprocessor-compatible and provide a safe, reliable, and cost-effective means of switching line voltage. Here, we discuss the application field and working principle of JS1A-B-12V relays.

Applications

JS1A-B-12V relays are widely used in large industrial automation systems, line monitoring, fault protection, and other electrical applications. They can be used to disconnect and switch large power applications, for example, switching of high power rotating machines. These types of relays are suitable for applications where power is conducted to motors, transformers, and pumps for controlling the operation of these systems. Furthermore, they are used in applications where power is conducted to solenoids, load shed relays, and others for precise current control. Additionally, JS1A-B-12V relays are used in electric arc furnace, power capacitor, harmonic filter, power isolator, and rectifier systems.

Working principle

JS1A-B-12V relays are electromechanical switches. The core of the relay is an electromagnetic coil. When a current passes through the coil, it electro-magnetically produces a force that moves a metal contact which then makes or breaks the electrical contact. The core of the relay is composed of a coil, an armature, and a contact point. The armature is a magnetically sensitive element, and when the electromagnetic coil is excited, the armature moves in response, closing or opening its contact point. The relay has a coil which is connected to a source of power and a contact device that includes a pair of contact points, which are either connected together or disconnected. The action of the relay is to either make an electric connection between the contact points, breaking the existing connection in the process, or to drop the connection between the contact points.

JS1A-B-12V relays are also designed to withstand high levels of current which makes them suitable for applications with a large electrical load. To ensure high performance and reliability, these types of relays also have several safety features including surge protection, transient voltage suppression, over temperature protection, over current protection, and contact protection. In addition, they offer a wide range of contact configurations with different contact materials for a wide variety of switching, monitoring, and control functions.

Thus, JS1A-B-12V relays are rugged and reliable electromechanical switches that are used to switch currents of greater than 2 amps, and offer a wide range of applications. They are widely used in distributed control systems and process control applications, and can be used to switch large power applications such as high power rotating machines. Furthermore, they have several safety features and offer a wide range of contact configurations for a wide variety of switching, monitoring, and control functions.
