Power Relays, Over 2 Amps
Power relays over 2 amps generally come in two basic categories: electromechanical relays and solid-state relays. Each provides a different method for the relay to open and close contacts, with each approach having its own unique advantages and disadvantages.
Electromechanical Relays
Electromechanical relays are generally the most reliable and versatile style of power relays capable of providing a wide range of current loads. In inductive loading applications, they can withstand over-currents, making them highly useful in industrial and electrical protection applications. They provide a bridge on circuits for control signals and power lines.At the heart of an electromechanical relay is an electromagnet, that consists of an iron core surrounded by a coiled wire, that is energized by an electrical current that allows an operator to open and close the contacts. Inside the relay there are several sets of contacts, usually two to provide an “open/close” function. The contacts can be used to switch on or off any power circuit, like a light switch. The actuation of the specific relay is what establishes the particular application or field of its use.
Solid-State Relays
Solid-state relays, unlike electromechanical relays, do not have moving elements, as they use semiconductor devices to open and close. They are triggered by a voltage or an electronically activated current, and do not require any external power to activate. They are capable of handling large loads, while being extremely reliable due to their lack of any moving parts.The main components of a solid-state relay include a photo-sensitive device, such as a Light Emitting Diode (LED) or an Infrared Diode (IRD), that turns on and off the current path; a resistor to limit current flow; and an insulated gate bipolar transistor (IGBT), that is the switching element of the transistor.
2963954 Application Field and Working Principle
The 2963954 power relays are specifically designed for use in electro-mechanical applications, such as motor starters, contactors and circuit breakers. It consists of an electromagnet with two contact points which can be opened or closed, depending upon the amount of current that passes through it. When adequate current is present, an armature is attracted, which pulls the internal contact points, closing the circuit. When the current ends, the armature is released and the same contact is re-orientated, bringing back the original position.
2963954 power relays are reliable and are often used in safety-related applications due to their ability to accurately detect a state change at a regulated time interval. They can also be used to initiate multiple functions in a system, and can help isolate or protect controlled systems. They can be utilized in industrial applications to control a variety of machine operations, including motor starters, contactors, solenoids, and more. This type of power relay makes use of two solenoids for its operation, one for the contactors and the other for the actuator armature.
Conclusion
Power relays over 2 amps are reliable, versatile, and offer a wide range of advantages depending on the application they are used in. Many of these relays, such as the 2963954 type, are designed with safety in mind, making them useful for industrial, electrical, and other applications. It is important to consider the type of current load, and various other factors when choosing the appropriate power relay, as each type has its own set of advantages and disadvantages for any particular application.
