2 Channel 5V Solid State Relay Module

The Solid State Relay (SSR) offers many advantages over the classic mechanical relay: it has a longer life, a considerably faster switch on/off speed, and no noise. It also has better vibration and mechanical shock resistance, as well as better moisture resistance.
This Solid State Relay Module includes four channels, each of which may work independently and be controlled. It is based on the Omron G3MB and is capable of controlling current up to 2A@240VAC.
