Release time:2025-08-13 15:09:43
A 24VDC relay is a crucial component in the field of electrical control systems, offering a simple yet effective solution for controlling circuits with different power levels. With its ability to switch between multiple circuits, it plays an essential role in automation, machinery, and various electronic applications. This article aims to explain what a 24VDC relay is, how it works, and the different applications where it is commonly used.
What is a 24VDC Relay?
A relay is an electrically operated switch that allows a low-power signal to control a high-power circuit. The 24VDC relay specifically operates with a 24-volt direct current (DC) power supply. When a 24VDC voltage is applied to the relay’s coil, it generates a magnetic field, which in turn activates or deactivates the mechanical contacts inside the relay. These contacts then control the flow of current in the connected circuit.
The relay typically has several contacts, including：
Normally Open (NO) contacts： These contacts are open when the relay is not energized and close when the relay is activated.
