The NL820A Isolator provides four channels of high level Signal Isolation and a ±13 volt (nominal) isolated supply to power separate preamplifier stages (eg NL822 or NL824). Connection of all four output channels to other four channel modules (NL134, NL135, NL136, NL144 and NL530) is provided via the Mother board and without need for external cables.
