Precautions for replacement
As the applicable thermocouples and
thermocouple compliance standards
differ, refer to Section 4.2.1 (2) to
check the specifications, and use the
thermocouple that can be used with
the Q64TD.
As they depend on the applicable
thermocouple and measured
temperature range, refer to Section
4.2.1 (2) to check the specifications.
Consider replacement with multiple
Q64TD.
The number of occupied I/O points
has changed to 16 points.
Wiring change is required.
