How can I interpret the primary and secondary pins of OEP 1200 1:1 600 Ohm isolation transformer. In the datasheet I cannot find it.
Find the attached file.
For a 1:1 transformer, the input and output are interchangeable.
In general, transformers do not have a direction of signal flow. Any winding can be used as an input. For example, if you apply 12VAC to the 12V winding of a 120VAC to 12VAC transformer, you will get 120VAC at the 120V winding.

According to this data sheet, the primary and secondary have a slightly different DC resistance. Makes it easy to use an Ohmmeter to tell which is which
Note that this transformer will tolerate only a small DC current in the primary; likely primary and secondary are wound with different size wire, hence the slight difference in resistance.
