A 24V relay is an essential electrical component used in various industrial and automation systems. It acts as an intermediary switch, enabling low-voltage control circuits to activate or deactivate higher voltage systems. This functionality makes the 24V relay indispensable in numerous applications, ranging from home automation to industrial machinery. This article will explore the working principle, types, applications, and common issues associated with 24V relays.
What is a 24V Relay? A 24V relay is a type of electromagnetic switch that operates when a voltage of 24 volts (either DC or AC) is applied to its coil. The coil generates a magnetic field when energized, which in turn pulls or pushes a set of contacts to either complete or interrupt the circuit. This allows the relay to control higher voltage circuits with a low voltage signal, providing both isolation and control in the process. These relays are commonly used in automated control systems, security systems, and even in everyday appliances like refrigerators and air conditioners. How Does a 24V Relay Work?
