The Omron G3TA-OA202SZ-US DC24 is a plug-in type I/O solid state relay designed for reliable output switching in control panels. It features a phototriac output with a zero cross function to minimize electrical noise during switching.
This model supports 24 VDC input control voltage and handles output loads from 0.05 to 2 A at 100–240 VAC. It comes with an integrated operating indicator for status visibility and uses a plug-in terminal structure for quick socket mounting. The black case is compact and suited for dense control boards.
Built for performance in industrial environments, the G3TA-OA202SZ-US offers high dielectric strength (4000 VAC) and operates reliably from –30°C to 80°C. With fast response times and minimal output voltage drop, it’s ideal for signal interface, heater control, or AC load switching in automation systems.
