Note
B7A Link Terminals with 10-points and B7A Link Terminals with mixed I/O (8 inputs/8 outputs) cannot be
connected to B7A Interface Units. Use 16-point B7A Link Terminals. 16-point B7A Link Terminals include
16-point models (input and output), models with 2 circuits configured with 16 points, and models with 16
points of mixed I/O.
