G3VM-61VY3 is an Omron solid-state relay (SSR). It is a zero-crossing type, meaning the output voltage changes from one state to the other when the input voltage crosses the zero volts mark. It has a 4A maximum rated current and is designed for use with DC-/Input of 4-32V DC. It has a DC-/Output of 5-110V AC. This SSR can be used in applications where a control device switches an AC load.
