Digital AC Input Modules
Description
Opto 22’s G4 AC input modules are used to detect on/off AC voltage levels.
Each module provides up to 4,000 V
rms
of optical isolation 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 AC input modules include sensing the presence or
absence of voltage with devices such as proximity switches, limit switches, float switches, selector switches, push
buttons, toggle switches, and thermostats. All modules include a built-in LED status indicator.
