Using terminal block converter module and dedicated cables
The temperature control module measures temperatures based on the temperature of the terminal block. Thus, depending on
the system configuration used, the temperature distribution of the terminal block is not uniform due to the effects of heat
generated from modules, and the measured temperature may greatly differ from the actual temperature. (especially when two
or more temperature control modules are connected next to each other or the temperature control module is mounted next to
the power supply module or CPU module).
In such cases, using the following terminal block converter module and dedicated cables reduces an error caused by the heat
generated.
(1): Remove the provided terminal block, and install the terminal block of the dedicated cable instead.
(2): Temperature control dedicated cable with Q terminal block
(3): Terminal block converter module for temperature control
(4): Thermocouple or compensation conductor
