PRECAUTIONS FOR USING THE QA1S6ADP-S1

6.1

Current Consumption of the QA1S6ADP-S1

Voltage (5VDC) is supplied to the QA1S6ADP-S1 from the power supply module on the main
base unit. Select the power supply module considering the current consumption of the
QA1S6ADP-S1. The current consumption of the power supply module on the main base unit
will be as follows.
Calculation formula
Current consumption of the module(s) on the main base unit + Current consumption of the module(s) on the
Q5B + Current consumption of the module(s) on the A1S5B + Current consumption of the QA1S6ADP-S1 
*1
n
*1 n indicates the number of adapters (QA1S6ADP-S1) in the system (including the one(s) mounted on the
A1S6B).

I Rated current of the power supply module on the main base unit
I0 Current consumption of the module(s) mounted on the main base unit
I1 to I3 Current consumption of the modules mounted on the extension base units (1st to 3rd level).
(In the system where the A1S6B is used, the current consumption of the module(s) mounted
on the extension base unit is supplied from the power supply module on the extension base unit.)
IA Current consumption of the QA1S6ADP-S1
In the system above, the QA1S6ADP-S1 can be used when the following condition is satisfied.
