DESCRIPTION
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.

G4OAC5A and G4OAC5AMA
Modules
All AC output modules are equivalent to single-pole, single-throw,
normally open contacts (Form A, SPST-NO) except the G4OAC5A5,
which is equivalent to a single-pole, single-throw, normally closed
contact (Form B, SPST-NC).
Each module is equipped with a 4 amp fast-blow fuse. The fuse
breaking capacity is 40 amps at 250 VAC. 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.
The G4OAC5MA and the G4OAC5AMA are special modules featuring a
manual-on/manual-off/automatic switch, ideal for diagnostic testing
of control applications.
Part numbers ending in FM are Factory Mutual approved.
Compatible with Raspberry Pi
