G4 I/O family
The G4OAC15 is a digital AC output module with an output voltage range of 12–140, requiring a typical logic voltage of 15 VDC. It is not for use with Opto 22 brains or with a Raspberry Pi, which use 5 VDC logic.
This AC output module is equivalent to a single-pole, single-throw, normally open contact (Form A, SPST-NO). It includes a 4 amp fast-blow fuse.
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.
Typical applications for AC output modules include switching loads such as AC relays, solenoids, motor starters, heaters, lamps, and indicators.
