IDEC MICROSmart FC6A Series User Manual page 55

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
utilization (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.
■ Relay output type
There are no usage restrictions for input and output I/O.
■ Transistor sink output type
There are no usage restrictions for input and output I/O when no cartridges are installed.

When a cartridge is installed, reduce the input voltage and I/O simultaneous ON ratio (a%) as shown in the following diagrams.
