Connection Restrictions When Expanding the PLC
Expansion modules, the HMI module, the cartridge base module, and cartridges on the basic expansion side operate with the internal
power supply that is supplied from the CPU module or the expansion interface remote slave module. Expansion modules on the
expansion interface side operate with the internal power supply that is supplied from the expansion interface module (expander).

The internal power supply current that can be supplied to the expansion modules on the basic expansion side, HMI module,
cartridge base module, and cartridges depends on the module supplying the power. Ensure that the total amount of current for the
expansion modules on the basic expansion side, HMI module, cartridge base module, and cartridges does not exceed the limit of
the internal power supply that can be supplied.
Notes:
A maximum of eight expansion modules can be connected on the expansion interface side, regardless of the internal power supply current
