Selecting The Power Supply Module - Mitsubishi Electric Q26UD(E)HCPU User Manual

7.2.3

Selecting the power supply module

The power supply module is selected according to the total of current consumption of the base units, I/O modules,
intelligent function module, special function module, and peripheral devices supplied by its power supply module.
For the internal current consumption of 5VDC of the base unit, refer to Page 223, CHAPTER 8.
For the internal current consumption of 5VDC of the I/O modules, intelligent function module, special function module,
and peripheral devices, refer to the Manuals of their respective modules.
For the devices obtained by a user, see the manual for the respective device.
(1) When the base unit is Q3B, Q3DB or Q6B:
Q series power supply
module (such as Q61P and
Q62P)
*1 The CPU module is mounted on the main base unit.
Keep the current consumption of the base unit (Q3B, Q3DB, and Q6B) below the 5VDC rated output
current of the Q series power supply module.
5VDC rated output current
(a) Precaution on using the extension base unit (Q5B, QA1S5B)
When the Q5B or QA1S5B is used, a power of 5VDC is supplied from the power supply module on the
main base unit through an extension cable.
Therefore, to use the Q5B or QA1S5B, pay attention to the following.
• Select a proper power supply module of 5VDC rated output current to be installed to the main base unit so
that it will cover the current used by the Q5B or QA1S5B.
For example, if current consumption is 3.0A on the main base unit and 1.0A on the Q5B or QA1S5B,
any of the power supply modules shown in a table below must be mounted on the main base unit.
5VDC rated output current
• Because 5VDC is supplied to the Q5B or QA1S5B through an extension cable, voltage is lowered in
the extension cable.
The power supply module and extension cable must be selected so that a voltage of 4.75VDC or higher is
supplied to the "IN" connector of the Q5B or QA1S5B.
For details of the voltage drop, refer to Page 88, Section 4.3.4.
