Working Principles

The ACNT-H870-500E is an optoelectronic isolation amplifier that utilizes a photovoltaic isolation technique. The input signal is converted into an optical signal, which is then transmitted across the isolation barrier. On the output side, the optical signal is converted back into an electrical signal for further processing. This isolation ensures that there is no direct electrical connection between the input and output circuits, providing protection against voltage spikes, noise, and ground loops.
