Can this also work on the PWM module?

If the ballast is 0-10v analog then you will need 0-10v dimming. PWM wouldn't work.

Is the RA no able to do analog dimming? How can I check if my RA is analog or PWM? I know I got the PWM expansion.

Look on the bottom of your relay box. I believe on the analog versions there is a sticker of some kind denoting this. PWM boxes have no sticker.

Newer dimming expansion modules are switchable between analog and PWM, 5 and 10v for each of the 6 outputs.

How will I be able to check if my PWM module is cable of doing analog?

Take off the cover. The newer one has jumpers to select 5 or 10v and analog or PWM for each channel.
