What is Relay Voltage?

    Relay voltage refers to the voltage required to activate or control he relay. It is primarily associated with two main voltage types： Coil Voltage and Contact Voltage. These two voltages are essential for understanding the working of a relay and ensuring compatibility with the systems they are designed to control.

    Coil Voltage： This is the voltage required to eergize the coil of the relay. When the relay coil is supplied with the appropriate voltage, an electromagnetic field is created, which in turn either opens or closes the relay's contacts. The coil voltage can be either DC (Direct Current) or AC (Alternating Current), depending on the type of relay. For example, common coil voltages include 12V DC, 24V DC, 120V AC, and 230V AC. Selecting the correct coil voltage is crucial, as applying a voltage that is too low may prevent the relay from operating, while excessive voltage could damage the coil.nt    Relays are widely used electromechanical devices that play a crucial role in automating circuits and controlling various systems. They act as switches that can either open or close a circuit depending on the voltage applied to their coils. A fundamental characteristic of relays is their voltage ratings, particularly the relay voltage, which dictates how the device operates. In this article, we will explore the concept of relay voltage, its importance, and how it affects the performance and reliability of a relay in different applications.
