16 Channel 5V Relay Module SPDT

455.00505.00

SKU: N/A Category:

The 16-Channel 5V Relay Module SPDT (Single Pole Double Throw) is designed to effectively control devices requiring higher voltages, surpassing the capacity of most microcontrollers like Arduino or Raspberry Pi. This relay module, with 16 channels, is capable of managing household appliances with a power rating of up to 10A.

Note: The PCB color or layout may have slight variations.

Understanding Relays:
A relay is an electrically operated switch. While many relays use an electromagnet to mechanically operate a switch, other operating principles, such as solid-state relays, can also be employed. Relays are essential in scenarios where it’s necessary to control a circuit using a separate low-power signal or when one signal must control multiple circuits.

Relays operate based on electromagnetism. When the relay coil is energized, it acts like a magnet and changes the position of a switch. Importantly, the circuit powering the coil is entirely isolated from the section responsible for switching ON/OFF. This isolation provides electrical separation. Consequently, it becomes possible to control a relay using a 5V signal from an Arduino while having the other end manage a 220 to 240V appliance. The higher voltage end is entirely isolated from the 5V Arduino circuitry.
