What is the function of an inductive relay?

An inductive relay functions by utilizing electromagnetic induction to operate a mechanical switch when it is energized. When current flows through the coil of the relay, it creates a magnetic field, which in turn attracts a movable armature or lever. This mechanical movement closes or opens the circuit, allowing or preventing current flow as needed. This capability makes inductive relays particularly useful in various applications, including control systems where remote operations or automated switching is required.

The operation of the inductive relay is fundamental in many electrical circuits, as it allows for low-power control signals to manage high-power loads safely. By using this mechanism, inductive relays help to protect sensitive components and ensure reliable operation in diverse electrical systems.
