Temperature
measurement range
and precision
• Thermoresistance type (ATI04A)
-50 to 300.0°C
Resolution 0.1°C
Overall precision ±1%FS
• Thermocouple type (ATI04B)
0 to 600.0°C
Resolution 0.1°C
Overall precision ±1%FS
Data sampling period
setting (NOTE)
• 0.3 s per two channels
• 0.5 s per four channels to 10 s per four channels
(4 s per four channels is assumed if no specification is
made)
System failure check • Self-diagnosis
A watchdog timer is used.
• Abnormal temperature (including sensor input
disconnection)
Failure information about each abnormal channel
is sent to the PMC.
Interface with the PMC • PMC → temperature module
Information format: Binary or bit
Signals: 32 points
• Temperature module → PMC
Information format: Binary or bit
Signals: 32 points

NOTE
The actual response time is the sum of the time
required for the signal to pass the filter and the scan
time that is determined depending on the system1
