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.
