Alerton TX-SA Control Circuit Board – Used, Fully Functional, Building Automation

Okay, so if you’re into building automation or HVAC controls, you probably know Alerton.

This is a used TX-SA control circuit board.

It’s been around the block—might have a few scuffs or signs of cosmetic wear—but electrically, it’s fully operational and works just like it should.

Could be a floor model or a store return, but it’s been tested and it’s ready to go back into service.

Perfect if you’re repairing a system, need a spare, or just want a backup board.

The part number is TX-SA, made by Alerton.

No fancy extras, just the board itself.

If you’re working on an older system and need a replacement without paying for new, this is a smart, budget-friendly pick.
