G4 I/O family
The G4IAC15A is a digital AC input module with an input voltage range of 180-280 VAC/VDC, 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.
Opto 22’s G4 AC input modules are used to detect on/off AC (or DC) voltage levels. Each module provides up to 4000 volts of optical isolation (transient) between field inputs and the logic output of the circuit.
All AC input modules are designed with filtering on the input and a hysteresis amplifier, providing high noise rejection and transient-free “clean” switching.
Typical applications for AC input modules include sensing the presence or absence of voltage, and sensing contact closure from sources such as proximity switches, limit switches, float switches, selector switches, push buttons, toggle switches, and thermostats.
