OPT G4IAC5
The G4IAC5 is a digital AC input module with an input voltage range of 90-140 VAC/VDC, requiring a typical logic voltage of 5 VDC. This module is compatible with Opto 22 brains and with a Raspberry Pi.
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.
