OPTO 22 G4OAC5 Digital AC Load Switch

The G4OAC5 is a digital AC output module designed for controlling and switching AC loads with high safety standards. It offers up to 4000V of optical transient isolation between the output and control circuitry, ensuring noise immunity and operator safety. The module features zero voltage turn-on and zero current turn-off, operating as a normally open contact (SPST-NO), and includes a removable 4A fast-blow fuse with a 40A break capacity at 250 VAC for overload protection. It can withstand an overcurrent surge of 80A for one cycle and functions reliably within -30°C to 70°C. The integrated LED indicator simplifies diagnostics, making it ideal for applications like relays, motor starters, heaters, lamps, and automation systems where reliable load switching is required.
