Description:

G3NA-225B-DC5-24 is an Omron solid-state relay that provides isolation between a DC control input and an AC load, delivering 25 A at 24–240 VAC in a single Form A (SPST-NO) output. The DC input accepts 5–24 V, enabling direct drive from common automation controllers, and a built-in varistor helps absorb voltage surges that can occur on the load side. The G3NA-225B-DC5-24 uses zero-cross switching to minimize EMI and inrush current when turning on inductive or resistive AC loads. Note that several distributors list the G3NA-225B-DC5-24 as obsolete and no longer manufactured, so if you need ongoing availability you may want to consider current G3NA variants or other Omron SSR families with equivalent ratings.
