Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

  • Description

    High-Speed Opto-Isolator


    Quick Facts

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

  • Further Details

    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 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 High-Speed Opto-Isolator protects devices with 115.2-kbps serial ports up to 1000 feet (304.8 m) on either side of the interface. If the interface doesn’t provide enough power, order the optional 120-VAC Wallmount Power Supply (PS1002).

    NOTE: To protect RS-232 to RS-422/485 lines, see our RS-232↔RS-485/422 Converter Plus with Opto-Isolation (IC108A).


    NOTE: To protect RS-232 to RS-422/485 lines, see our RS-232↔ RS-485/422 Converter Plus with Opto-Isolation (IC109A-R3).
