System Construction
The Analog Input Unit occupies many words and consumes a large current.
Therefore when constructing systems incorporating Analog Input Units, the user
should take the following into consideration.
1-4-1 Total Number of I/O Words
The maximum number of available I/O words for each system varies with the
CPU Unit. Refer to the following table.

The Analog Input Unit usually occupies four input words. On the other hand, the
Analog Power Supply Unit does not use any I/O words. The total number of
words for each system must not exceed the above maximum number of I/O
words.
If the Analog Input Unit has one or two analog inputs, turn OFF pin 9 of the Ana-
log Input Unit’s DIP switch so that the Analog Input Unit will occupy only two
words.
1-4-2 Total Current Consumption
The following is the capacity of each available Power Supply Unit, from which
power is supplied to a whole system.
Model
Capacity
CQM1-PA203
5 VDC, 3.6 A, 18 W
CQM1-PA206,
CQM1-PA216
5 VDC, 6.0 A
24 VDC output, 0.5 A
Total: 30 W
CQM1-PD026
5 VDC, 6 A, 30 W
The following table lists the current consumptions of the Analog Input Unit and
Analog Power Supply Units. Refer to the CQM1H Operation Manual (W363) or
the CQM1 Operation Manual (W226) and select the most suitable Power Supply
Unit for your CQM1H/CQM1.

Caution
The total current consumption of each system must not exceed the capacity of
the Power Supply Unit to be used.
