G4IAC5 Module
DESCRIPTION
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.
The G4IAC5MA is a special module featuring a manual-on/
manual-off/automatic switch, ideal for diagnostic testing of
control applications.
Typical applications for G4 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.
Compatible with Raspberry Pi
The following G4 digital AC input modules can be used with the
Digital I/O Carrier Board for Raspberry Pi® (part number OPTO-P1-40P)
