PB1650ADC1.1 Block Diagram
At the top of the diagram, you can see the eight analog inputs, and, moving
down, the signal conditioner and the analog/digital converter. The signals pass
to the shift register via optocouplers (i.e. fully electrically isolated) and from
there to the VMEbus interface of the basic board. The control logic is part of
the piggyback. It controls the converters and shift registers, passing the data to
the ES1650.1 Piggyback Carrier Board.
