4 Channel 5V Low Level Solid State Relay Module 
 

Solid State Relay - Solid State Relay (SSR) has advantages such as more efficient switching speeds, more stable operation against electrical noise, longer service life, resistance to physical vibrations and resistance to moisture, which distinguish this type of relay from ordinary mechanical relays. These relays are preferred in places that require fast and precise operation such as computer peripherals, medical devices. To learn more about relays, you can read our blog post by clicking here. 

It can control AC voltages between 100 and 240V up to 2A current. The module can be controlled from a 5V digital source. A resistive type fuse is provided on the module to help protect the overcurrent draw.
