Working Principles

The ASI4UE-F-G1-ST utilizes galvanic isolation technology to separate the input and output signals electrically. It employs optocoupler-based isolation, where an LED on the input side emits light that is detected by a photodetector on the output side. This ensures that any electrical noise or voltage spikes on the input side do not affect the output side, providing reliable signal isolation.
