No, the AIU is used for sensor feedback and switch feedback, if wired to do so. Each block sensor is fed to the AIU to trigger one of the AIU¡¯s 16 channels (actually 14 because 2 channels are too sensitive unless it¡¯s turnout feedback).
Not to pick but a clarification. ?12 of the 14 AIU channels have good sensitivity except for #6 & #7, for which I created a modification to improve their sensitivity. I posted the fix on the NCE group.
