5V 1 Channel 240VAC Relay Module

5V 1 Channel 240VAC Relay ModuleA Relay is a digital switch to control much higher voltages and currents than your normal Arduino boards does. When inputs a logic voltage, the relay will switch to allow current to flow or cutoff, depending on your wiring.

Components of a Relay:

• Coil
• Common terminal
• Normally closed terminal
• Normally open terminal

When the coil is energized, the common terminal and the normally open terminal will have continuity.

Why Use a Relay:

Anytime you want to switch on/off a device which draws more current or works with a high voltage, you’ll need to use a relay, such as controlling of headlights, parking lights, horns, etc.

Specifications:

• Control Voltage: 5V DC
• High Input voltage trigger
• Arduino Friendly
• Max Control Capacity: 10A@250VAC or 10A@30VDC
