The G3NA-205B BUTUDC524 is a type of solid-state relay manufactured by the Omron Corporation. This relay is a 5-pin AC input type, with a rated operational voltage of 24 to 240 VAC, a maximum current rating of 2A, and a maximum switching voltage of 200VAC. The product also features zero cross-over technology, which allows for zero-volt switching to avoid damage to the load. Additionally, it has a built-in diode for reverse current protection and a 1.5KV dielectric strength for a higher level of protection. This relay is used for motor control, lighting control, heating control, and other applications requiring high switching capability and reliability.
