(3) Mountable main base unit, mountable power supply module, number of
mountable modules
Mount the MELSECNET/H remote I/O module on the CPU slot of a main base unit.
(4) Applicable extension base unit
The system including the MELSECNET/H remote I/O module can be extended using extension base units.
*1 Calculate the operating voltage of the extension base unit used and check that the voltage is within the rating.
*2 When using extension cables, pay attention to the following.

• For the calculation formula, refer to the QCPU User's Manual (Hardware Design, Maintenance and Inspection).
• For the current consumption of each module mounted on the extension base unit, refer to the manual for each
module used.
• Do not install extension cables together with the main circuit lines (high voltage and large current).
• Connect a cable between the OUT connector of an extension base unit and the IN connector of the next-level
extension base unit.
