GECB stands for Global Elevator Control Board, which is the computing core of the Otis GCS control system. It is also known as the Otis elevator control board, the Otis elevator printed circuit board, the Otis elevator circuit board and the Otis control board.
Q3: What is included with this GECBII-LV PCB?
A: The GECBII-LV PCB is supplied including the board GAA26800RF3, which is the GECB2_LV control board. The computing core ABA26800AVP6 and the LVPB power board GCA26800PM1 are separate parts of the same control system. Please confirm which parts of the set your controller needs before ordering.
Q4: What is the difference between GAA26800RF3 and GAA26800RF1?
A: GAA26800RF3 and GAA26800RF1 are two versions of the GECB2_LV control board.
