Hello again!

Thank you for patiently waiting, Upon investigating, we have created this module following the standard pinning depicted on page 5 of the datasheet available here:
https://www.tracopower.com/sites/default/files/products/datasheets/thm10_datasheet.pdf.

Please refer to the outline dimensions section where it establishes the pinout for a single output.

Let me know if you have any further questions, we are here to help.

Have a great day!
