advantages of relay circuits

Relay circuits offer several benefits that contribute to their widespread usage in diverse fields. These advantages include:

Electrically Isolated Control: One of the primary advantages of relays is their ability to electrically isolate the control circuit from the high-power circuit. This isolation ensures that low-voltage control circuits (such as microcontrollers or switches) do not come into direct contact with high-voltage circuits, enhancing both safety and reliability. Remote Control Capabilities: Relays enable remote control of electrical devices, which is particularly useful in automation and control systems. Operators can control a device from a distance without being exposed to potentially dangerous high-voltage circuits.
