This is especially helpful in health care equipment in which the signals from a low-voltage sensor circuit (commonly battery-driven) in contact with a dwelling organism must be electrically isolated from any achievable electrical failure inside a recording or monitoring system functioning at possibly unsafe voltages. An optoisolator also lets information be transferred in between circuits that do not share a common ground potential.
