Power Relays, Over 2 Amps

A 1479670000 is a power relay that has a current capacity of over 2 amps. It’s a type of electromechanical switch that consists of a coil and a set of contacts that can be opened or closed by the energizing or de-energizing of the coil. Unlike switches that can be opened and closed directly by hand, these relays are mainly used to allow a low voltage control circuit to control the activation of a high voltage circuit by being activated through an electrical or magnetic signal.

As with any power relay, its primary purpose is to bridge the gap between a low voltage control circuit and a high voltage electrical circuit. This allows for the control of electrical devices over a much stronger flow of current than that provided by the control circuit, and without the direct manual operation of the respective electrical circuit’s switches. This makes it possible to operate high voltage machines from remote locations.

Application Field

A 1479670000 is mainly used in manufacturing, industrial controls and robotics. Its most common applications are in door and window openers, security systems, machine tools, curtain motors, and electrically operated door locks. The relay can also be used to control and switch between multiple power sources and to handle signal interfacing between two electronic systems.

Working Principle

When the control circuit energizes the coil, it activates the relay\'s internal magnetic field. This triggers the contacts to either open or close, depending on the type of relay. Relays usually have a set of single pole, single throw (SPST), double pole, single throw (DPST) or double pole, double throw (DPDT) contacts, which enable them to either break or create a connection between two terminals. The contacts can also be configured in combinations that enable the magnetic field to operate the circuit in more complicated ways.

The current capacity of a 1479670000 relay is determined by the amount of current that the magnetic field can handle without becoming saturated. As the current passing through the contacts increases, the magnetic field gets weaker, and the contacts will open more easily. Over time, due to wear and tear, the contacts will weaken and, eventually, be unable to switch reliably at the rated current.
