The 12V 8 Channel Relay Module provides reliable switching with a 12V input voltage and a maximum current rating of 10A. It features a 8 channel relay module with optocoupler, and three terminals (NO, NC, COM). This module is suitable for switching between 250VAC, 125VAC, 30VDC, or 28VDC electrical circuits.
This Module provides a stable and reliable control of electrical devices. It is great for applications such as motor, lighting and other circuit control thanks to its 12V input voltage and 10A current rating. Electrical systems with this module will enjoy reliable and stable control. The use of such high-voltage relay eliminates the risk of heating up of the relay as electromechanical relay limit the current consumption in accordance with a voltage rating.
A 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. A Relay usually consists of a coil, 1 common terminal, 1 normally closed terminal and one normally open terminal. When the coil is energized, the common terminal and the normally open terminal will have continuity.
