Connecting Modules to the CPU Module
The internal power supply current that can be supplied from the CPU module to the expansion modules on the basic expansion
side, HMI module, cartridge base module, and cartridges is as follows.
*1 The number of modules that can be connected on the basic expansion side does not include the expansion interface module (expander). When
using the expansion interface module (expander), add the following current.
*2 Only the following number of communication modules can be connected to the CPU module, regardless of the internal power supply current
that can be supplied from the CPU module.
*3 Only an analog I/O cartridge can be connected.
*4 When an expansion interface remote master module (FC6A-EXM1M) is connected to the basic expansion side, a maximum of five modules can
be connected on the basic expansion side.
*5 The internal power supply for the internal 5 V line is used to run the expansion modules (basic expansion side), the HMI module, and the
cartridges. Calculate the total current that is used by the modules and ensure that the limit is not exceeded. For details, see "Internal Power
Supply Current of the Modules and Cartridges" on page 3-36.
*6 The internal power supply for the internal 24 V line is used to drive the output module relays and transistors. Calculate the total current when
the outputs are simultaneously ON with the following values as the current per output and ensure that the limit is not exceeded.
• Relay output: 6 mA/point
• Transistor output: 1.5 mA/point
Connecting Modules to the Expansion Interface Remote Slave Module
A maximum of seven expansion modules can be connected on the basic expansion side, regardless of the internal power supply
current that can be supplied from the expansion interface remote slave module.

The CPU module cannot detect the internal power supply current that the expansion modules are using. Observe the
restrictions in this section because malfunction or failure may result if the FC6A Series MICROSmart is continuously used
when the current exceeds the limit.
