OP5971 DB37 to SMB Adaptor

Page Content

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.

For more information about the use of Vuser and Vrtn pleaser refer to this article in the OPAL-RT knowledge base : How to power the different DB37 boards for digital outputs.

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.
