[Example]
Example in which the maximum number of function modules (mainly TIO modules) is mounted at a
power supply voltage of 12 V.
z z z z When TIO-D modules are mounted together with other function modules
As the TIO-D module consumes an output current of 80 mA/slot and the TIO-B module, an output
current of 40 mA, the following current is obtained.
For TIO-D (3 modules): 80
×
3 = 240 mA ,
For TIO-B (4 modules): 40
×
4 = 160 mA
The above current does not exceed the maximum power supply capacity (1000 mA). However, as one
TIO-D module is assumed to correspond to two function modules,
up to 7 function modules can be
mounted.
