OPT-G4OAC5A5

G4OAC5A5 G4 AC Output, 24-280 VAC, 5 VDC Logic, Normally Closed

Opto 22’s G4 AC output modules are used to control or switch AC loads. Each module provides up to 4000 volts 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. This AC output module is equivalent to a single-pole, single-throw, normally open contact
(Form A, SPST-NO).

Typical applications for AC output modules include switching loads such as AC relays, solenoids, motor starters,
heaters, lamps, and indicators.
