A 24V DC Industrial Relay is an electromagnetic switch that operates on a 24V DC control voltage. The primary function of a relay is to open or close electrical circuits, allowing a low-power signal to control a high-power circuit. When a 24V DC current is applied to the relay's coil, it generates a magnetic field that moves a set of contacts. This action opens or closes the contacts, thereby controlling the connected load, such as motors, lights, or other equipment that requires higher voltages or currents.

    Relays come in various configurations, including single-pole and double-pole models, and may have different contact arrangements like SPDT (Single Pole Double Throw) or DPDT (Double Pole Double Throw). The 24V DC relay is widely used in systems that require low-voltage control signals but need to manage high-power loads.
