Opto-Isolator II

• Internal fiber optic air gap prevents ground loops.
• Data signals are converted to line pulses inside the Opto-Isolator and continue along the circuit.

Linking two devices powered by separate AC sources can create the potential for a ground-loop surge—a damaging electrical condition that can destroy your computer and wipe out data. But BLACK BOX® Opto-Isolators interrupt that lethal pathway by completing the connection between the two devices with an internal fiber optic link.

Data signals, converted to light pulses inside the Isolator, continue along on the circuit. But the fiber optic air gap stops ground loops from wreaking havoc with your hardware.

Our Opto-Isolator II has an RS-422/485 interface and a 4-screw terminal instead of RJ-45 ports. It protects lines up to 2000 feet (609.6 m).
