The NI SCXI-1328 is a temperature sensor terminal block designed to connect thermocouples and RTDs directly to SCXI data acquisition modules within the SCALABLE modular I/O platform. It provides screw-terminal connections for secure sensor wiring and integrates cold junction compensation for thermocouple measurements and lead wire resistance compensation for RTD measurements. The terminal block minimizes electromagnetic interference to deliver accurate temperature data in industrial, laboratory, and research environments.
