REPLACING POWER SUPPLY MODULES

4.3 Precautions for Replacement of the CPU Module

(1) The current consumption of the Q series and the A0J2H series differ. Calculate the current
consumption of the entire system to select the power supply module.
(2) The wires and solderless terminals that can be used on the Q series terminal block differ from
those that can be used on the A0J2H series. Use wires and solderless terminals that match
the specifications.
(3) The Q61P and Q62P (input power supply) is the wide range type. The modules support the
operating voltage of 100VAC and 200VAC.
(4) When the Q62P (5VDC output current: 3A) has insufficient current capacity, it is recommended
to use Q61P (5VDC output, current: 6A) or Q64PN (5VDC output, current 8.5A).
However, as these power supply modules do not output 24VDC, it is necessary to separately
prepare a commercially available 24VDC output power supply.
