The PXIe-4353 is a thermocouple input module that provides integrated data acquisition and signal conditioning for temperature measurements. The PXIe-4353 includes increased accuracy and synchronization features for scalable measurement systems from low- to high-channel counts. The high accuracy is attributed to the NI TB-4353 isothermal terminal block that optimizes thermal conductivity between the thermocouple terminals and the cold-junction compensation (CJC) channels. The PXIe-4353 has two auto zero channels for offset compensation as well as open thermocouple detection to identify disconnected thermocouples.
