Non-Isolation Considerations
The board is non-isolated, since there is electrical continuity between the
logic and field I/O grounds. As such, the field I/O connections are not
isolated from the system. Care should be taken in designing installations
without isolation to avoid noise pickup and ground loops caused by multiple
ground connections.
