Remarks
Each pair of Inputs 1 and 8, 2 and 7, 3
and 6, and 4 and 5 is the analog inputs
of ADC (Analog-Digital Converter).
So, when a digital input module such as
the D-001T is inserted into Slot 1, for
example, the digital input selector DIS1
is switched over to the DIGITAL position,
thereby disabling the use of analog
Inputs 1 and 8.
Consequently, Slot 8's analog input
(AIN) cannot be used.
Likewise, when Slot 2 is occupied by the
D-001T, Slot 7's analog input cannot be
used; and when Slot 3 is occupied, Slot
6's analog input cannot be used.
