*1 Current consumption at each extension base unit is as follows:

First extension base unit: None

Second extension base unit: IA+I2

Third extension base unit: IA

Since the first extension base unit and the third extension base unit are

supplied from the power supply module on each extension base unit, the

values are not included above.

Since the current consumptions I1 to I3 vary depending on modules to be

mounted, refer to the manual for the module to be mounted.

The minimum value of the 5VDC output voltage of the power supply module

mounted on the main base unit is set to 4.90VDC. Therefore, the voltage of

the IN side connector of the QA6ADP+A5B/A6B in the final stage is

4.75VDC or more only when the sum (V) of voltage drop is 0.15V or less.

V = V1 + V2 + V3 = R1 (I2 + IA 2) + R2 (I2 + IA 2) + R3 IA
