There is an isolated DC / DC converter TMR1222
- 12VDC will come to the input,
The outputs will be + 12VDC and -12VDC
When connecting with dual output, there is a "Common" contact
Tell me, is this the earth? If so, why was it not called GND?
Can I connect Common to GND?
Thank you!

The Traco TMS 2 series are isolated converters, so "ground" on the input side is, well, isolated from "common" on the output side. Another company may have called them "input return" and "output return".
Yes, you can tie them together. The two sides will no longer be isolated (in which case you may want to see if you can use a non-isolated module that costs less), but the thing should work just fine.
