Solid State Relay is a non-contact electronic switch module that has relay features. Based on Omron G3MB, this solid relay module can be used to control current upto 2A@240VAC. Compares with the traditional relay, the solid relay module has better resistance to vibration and mechanical shock, and better moisture proof performance. It 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.
