The G4OAC24 is a Digital AC Output Module is used to control or switch AC loads. This G4-series module provides up to 4000V of optical isolation (transient) between field outputs and the control side of the circuit and each features zero voltage turn-on and zero current turn-off. It is equipped with a 4A fast-blow fuse. The fuse breaking capacity is 40A at 250VAC. Current should be limited to prevent the short circuit current from exceeding the rated breaking capacity of the fuse. Typical applications for AC output modules include switching loads such as AC relays, solenoids, motor starters, heaters, lamps and indicators.
