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 a Black Box Opto-Isolator interrupts that lethal pathway by completing the connection between the two devices with an internal fibre optic link.
Data signals, converted to light pulses inside the Isolator, continue along on the circuit. But the fibre optic air gap stops ground loops from wreaking havoc with your hardware.
Our High-Speed Opto-Isolator protects devices with 115.2-kbps serial ports up to 304.8 m on either side of the interface.
NOTE: To protect RS-232 to RS-422/485 lines, see our RS-232↔RS-485/422 Converter Plus with Opto-Isolation (IC108A).
