Which details identify this version?

Compare ADN512UB-A90 with the original label and two red/black leads and white termination. Similar housings do not establish interchangeability.

Do the wires prove PWM or speed sensing?

No. Lead count and printed model wording alone do not establish signal functions or pinout. Confirm these and the mounting dimensions for the required version.
