Current consumption
Power of extension devices is supplied from the CPU module, powered input/output module or extension power supply
module.
The number of extension devices that can be connected must be determined from the capacity of the power supply.
For details on the current consumption, refer to Page 69 Limitation on Current Consumption.

Power supply from CPU module
*1 Power is supplied to input circuit of input modules by 24 V DC service power supply or external power supply.
However, the DC power type does not have 24 V DC service power supply.
Limitations when using extension devices
■Modules of extension connector type
FX5-CNV-IF is required to use modules of extension connector type.
■Limitations on high-speed pulse input/output module
Up to four high-speed pulse input/output modules can be connected in a system.
■Bus conversion module
• A bus conversion module is required to use FX3 extension module. FX3 extension module can be connected to the right
side of the bus conversion module only.
• For limitation on the number of connectable modules, refer to Page 65 Connection to the bus conversion module
(connection with FX3 extension devices).
■Limitations on intelligent function modules
Note that some intelligent function modules have limitations on the number of modules, order and combination in which they
are added for each individual module.

■Using the extended extension cable
• The connector conversion adapter is required when the extended extension cable connection destination is a module of
extension cable type (except for FX5-1PSU-5V or extension power supply module).
• When connecting a bus conversion module in the same system, connect FX5-1PSU-5V or the powered input/output
module directly after the extended extension cable.
• This cannot be used with the FX3 extension module.

Limitations
Only one module may be connected per system.
One module can be connected to the system for each station type.
• Master station: 1
• Intelligent device station: 1
When using the FX5-CCL-MS as the master station, it cannot be used together with the FX3U-16CCL-M.
When using the FX5-CCL-MS as the intelligent device station, it cannot be used together with the FX3U-64CCL.
Only one module may be connected per system.
Use together with the FX3U-128ASL-M is not possible.
Up to two modules connectable per system.
When FX3U-1PSU-5V is not used, connect immediately after the bus conversion module.
Only one module may be connected per system.
When using the FX5-CCL-MS as the master station, it cannot be used together with the FX5-CCL-MS.
Only one module may be connected per system.
When using the FX5-CCL-MS as the intelligent device station, it cannot be used together with the FX5-CCL-MS.
Only one module may be connected per system.
Use together with the FX5-ASL-M is not possible.
