The Q64TC measures a temperature on the basis of the temperature of a terminal
block. Therefore, depending on a system configuration (especially for the case when
two or more the Q64TC are mounted side by side, or when the Q64TC is mounted
next to the power supply module or the CPU module), the temperature distribution of
the terminal block becomes inhomogeneous because of the effect of heat emitted from
each module, thus the measured temperature error may become large.
In such case, use a terminal block converter module and a dedicated cable shown
below to prevent the error caused by the heat emission.
The following table lists the dedicated cable and the terminal block converter module.
