The following tables provide the general pin assignments for the OP48H10 DB37 connectors.

Detailed pin assignments for all connectors can be found in the System Description document provided with your order, or refer to the general pin assignment of your specific unit.

Before designing cables, OPAL-RT recommends using the guideline Simulator EMC cable recommendations.

Digital Inputs and Outputs

The 32 digital I/O (DIO) on the OP48H10 module can be configured as inputs our outputs by groups of 8 (4 banks of 8 IOs). DIOs uses connectors P1 and P2 and are numbered from DIO00 to DIO31.
