2.6 Specifications for Module Combinations
The specifications when iC9200 modules are combined is given next.
2.6.1 Specifications and Restrictions for iC9200 Module Combinations
There are restrictions in the order in which you can connect the modules. Build the rack by connecting each mod-
ule in the order that is shown below.
Item Description
Maximum Configuration of iC9200
Controller
• Maximum number of racks: 1
• iC9200: One unit only in the controller system.
Maximum Configuration of I/O Modules
• 64 modules maximum (Including SLIO expansion master module and SLIO expansion slave
modules for expansion. The maximum number of units is 56 modules when using 4 racks,
the maximum number of expansion I/O racks.)
Note that the SLIO power supply module is not counted in the number of I/O modules.
• Maximum number of expansion racks: 4
2.6.2 Current Consumption and Rack Width Restrictions
When mounting multiple I/O modules, make sure the following conditions are met.
(1) Current Consumption
Output current of the power supply section
*1
≤ rated current of the power supply section (3 A)
*1 This is the total of the maximum internal current consumption of all I/O modules that are mounted to the iC9200.
Note:
The power supply section of the iC9200 has an overcurrent protection function to protect the equipment.
If the rated current of the power supply section is exceeded, the protection function will activate and the power supply to the system will be
shut OFF.
Configure the I/O modules so that the power supply capacity is satisfied by adding power supply modules as necessary.
Ensure that the overcurrent protection function does not activate by referring to the manual for each connected module and checking the cur-
rent consumption in advance.
(2) Rack Width
The unit width of the iC9200 (model number: JEYRM-MPX022□□10L32-□) is 70 mm.
Also consider the width of the SLIO I/O series modules that you will use, and select a DIN rail with a length 25
mm or longer than the rack width.
<Example>
A rack with the configuration shown in the following diagram has a rack width of about 138 mm.
