OP8666 Digital Input Connectors
Note
Both DB37 and DB50 connectors have the same electrical connection; therefore inputs can only be connected to either of them at the same time.
But the corresponding pin of an input on a connector can be used for monitoring on the other connector.
Information
The DB37 connector pin mapping directly matches the ones found on OPAL-RT's line of simulators and I/O expansion units.
