Can lighting control panel take both 120V and 277V lighting circuits?
300.3.C(1) may allows? Thank you.
 
Yes also take a look at 200.6(D) which would apply when you had 120 and 277 volt circuits.

What're about 404.1 and 404.8(B) rules? Will barrier still required between 120V and 277V circuit relays even they are less than 300V?
 
404.8(B) is for adjacent snap switches. A relay is not a snap switch so no barrier is required.
