Understanding the 5V Relay Module and Its Applications
A 5V relay module is an electrically activated switch commonly used in switching circuits for home automation projects, controlling heavy loads, safety circuits, and automotive electronics. This small relay board works with a 5V signal and can handle up to 10A of current for both AC and DC loads. It offers compact 5-pin configuration with plastic molding, making it suitable for various applications.

RELAY RELAY
RELAY RELAY A relay relay is an electrically activated switch. 5V Relay Module 10A. This small Relay Board works from a 5V signal. It uses a transistor to switch the relay on so can be connected directly to a microcontroller pin. When the relay is not activated, the common pin is in contact with the NC pin and when it is activated, the common pin will break away from contact with the NC pin and subsequently makes contact with the NO pin.

Trigger Voltage (Voltage across coil) : 5V DC Trigger Current (Nominal current) : 70mA Maximum AC load current: 10A @ 250/125V AC Maximum DC load current: 10A @ 30/28V DC Compact 5-pin configuration with plastic moulding Operating time: 10msec Release time: 5msec Maximum switching: 300 operating/minute (mechanically)
Commonly used in switching circuits. For Home Automation projects to switch AC loads To Control (On/Off) Heavy loads at a pre- determined time/condition Used in safety circuits to disconnect the load from supply in event of failure Used in Automobiles electronics for controlling indicators glass motors etc.
