- NTB/3TB terminal-board function for compatible AC2000 and DC2000 controls
- Field-wire transition through a narrow GE 531X board format
- Exact PG1 group, drawing, jumper, and point-map verification required
531X305NTBAPG1 connects field and cabinet circuits to internal control hardware in the compatible AC2000 or DC2000 arrangement documented for the installed system.
The PG1 group, terminal population, jumpers, and connector routes distinguish this board from similarly named NTBA variants that may not be electrically interchangeable.
Replacement control starts with every energy source and wire identity, continues through continuity and independent review, and ends with individual proof of each drive signal and interlock.
Availability, condition, price, and shipping time for 531X305NTBAPG1 are confirmed during quotation.
