Description
The OP5971 was designed as a convenient solution to connect each individual channel routed through OPAL-RT’s standard DB37 I/O connector.
There is no signal conditioning or any impact on the signals. The OP5971 simply passes signals through the DB37 to SMB.
Pin Assignments
The table below gives the pin-out of the DB37 I/O connector and the corresponding SMB pin-out Note that all SMB connectors are referenced to the same GND.
DB37 Pin | Standard DB37 Pinout | SMB Pinout | DB37 Pin | Standard DB37 Pinout | SMB Pinout |

It is important to note a difference in the GND connections when using the DB37 to SMB adapter as this may impact isolation.
Using with Digital Outputs
When using this adapter with digital output signals, users must provide an external power supply. Use connector P4 at the bottom right to connect the power source.
