Compares with the traditional mechanical relay, the Solid State Relay (SSR) has many advantages: it has a longer life, with a much higher turn on/off speed and no noise. Besides, it also has better resistance to vibration and mechanical shock and better moisture-proof performance. This Solid State Relay Module has two channels, which work and be controlled separately. it is based on Omron G3MB, to control current upto 2A@240VAC, can be widely used in various areas such as computer peripheral interfaces, temperature/speed light adjustment, servo control, petrochemical, medical instrumentations, financial devices, coal, meters, traffic signals, etc. There are also modules with single channel, 4 channels and even 8 channels for your choice.
