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 56 Limitation on Current Consumption.

Power supply from CPU module
*1 Power is supplied to input circuit of input modules by service power supply or external power supply.
However, the DC power type does not have service power supply.
Limitations when using extension devices
■Connector conversion module
A connector conversion module 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 53 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 and order 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 an input
module/output module (extension cable type), high-speed pulse input/output module or an intelligent function module.
• When connecting a bus conversion module in the same system, connect the powered input/output module or FX5
extension power supply module directly after the extended extension cable.
• This cannot be used with the FX3 extension module.
