TBX-1303 32-Channel Isothermal Terminal Block
Table 1 shows the terminal block switch settings.
Note
On the SCXI-1102/B/C module, MTEMP mode is the only supported mode.
Temperature Sensor Output and Accuracy
The TBX-1303 temperature sensor voltage output varies from
1.91 to 0.58 V over the 0 to 55 °C temperature range. The temperature
sensor output accuracy is shown in Table 2.
To select and read the temperature sensor, refer to the driver software
documentation for programming information.

Includes the combined effects of the temperature sensor accuracy and the temperature
difference between the temperature sensor and any screw terminal. The temperature sensor
accuracy includes tolerances in all component values, and the effects caused by
temperature, loading, and self-heating.
