Connection Example 2
This example describes the number of connected modules, the internal 5 V Line Current, and the internal 24 V line current when
the expansion modules, HMI module, and cartridges in the below diagram are connected to the 40-I/O type.

Number of connected modules
For the 40-I/O type, the number of modules that can be connected must be seven expansion modules (basic expansion
side), one HMI module, and three cartridges or lower. There are seven expansion modules (basic expansion side), one HMI
module, and two cartridges, so there is no problem because the maximum number of modules was not exceeded.
 Internal 5 V line current
The current must be 1,070 mA or lower. The total current is 1,065 mA, so there is no problem because it does not exceed
1,070 mA.

Internal 24 V line current
The current must be 270 mA or lower. The total current is 336 mA, which exceeds 270 mA.
Program the PLC so that 45 or fewer relay outputs turn ON simultaneously (270 mA or lower = 6 mA × 45 points) or use the
expansion interface module (FC6A-EXM2) and connect the digital output modules with an insufficient amount of current to
the expansion interface side.
