Ambient Temperature, Input Voltage, I/O Simultaneous ON Ratio
When the FC6A Series MicroSmart is used in an ambient temperature of 45°C or higher, reduce the input voltage and I/O
simultaneous ON ratio (a%) according to the following diagrams. However, the following diagrams show the temperature
conditions when the FC6A Series MicroSmart is normally installed.
Note: Normally installed means the state in the diagram in "Normal Installation State" on page 3-1.
The usage conditions will also change according to the installation state. For details, see "Installation Location" on page 3-1.
I/O Simultaneous ON Ratio (a%)
FC6A-M08BR1 FC6A-M24BR1
FC6A-M08BR1 I0 to I3 There are no usage restrictions for input and output I/O.
FC6A-M24BR1
I0 to I7
I10 to I17
Set the usage ratio of the inputs (ON status) to a% or lower according to the conditions in the above
graph.
