Relay voltage refers to the electrical potential required to activate or deactivate a relay. In simple terms, it is the voltage applied to the relay's coil to initiate its switching mechanism. When the relay is energized by this voltage, the electromagnetic field created within the coil causes the relay's armature to move, closing or opening the circuit. This change in the circuit state allows relays to control high-voltage systems with low-voltage inputs, which is critical in numerous applications.

    Types of Relay Voltage

    Relays come in different voltage ratings depending on the voltage level required to operate them. These can be categorized primarily into two types: AC relay voltage and DC relay voltage.
