**Note on Isolation: Opto-Isolators and connectors are rated for at least 500V, but isolation voltage
breakdowns will vary and is affected by factors like cabling, spacing of pins, spacing between traces on
the PCB, humidity, dust and other environmental factors. This is a safety issue so a careful approach is
required. For CE certification, isolation was specified at 60V DC or AC rms. The design intention was to
eliminate the influence of common mode. Use proper wiring techniques to minimize voltage between
channels and to ground. Tolerance of higher isolation voltage can be obtained on request by applying a
conformal coating to the board.
