NI 9214

16-Channel Isothermal Thermocouple Input Module

Configure Page for: Print PDF Rich Text
  • Isothermal terminal block (included) for measurement accuracy up to 0.45 °C
  • Several cold-junction compensation (CJC) sensors
  • 250 Vrms channel-to-earth ground safety isolation
  • Autozero channel for offset error compensation
  • 24-bit ADC for up to 0.02 °C measurement sensitivity
  • J, K, T, E, N, B, R, and S types supported


The NI 9214 is a high-density thermocouple module for NI C Series carriers designed for higher-channel-count systems that also need higher accuracy than the NI 9213 offers.

The NI 9214 has several features that increase overall accuracy including the following:
- Front-mounting metal terminal block (NI TB-9214)
- Several CJC sensors in the terminal block
- Component layout to minimize thermal gradients

You can use up to eight NI 9214 modules in an NI CompactDAQ chassis or CompactRIO chassis for 128 thermocouple measurements in a single chassis.

Each shipping kit contains the following:
-NI 9214 module with spring-terminal connectivity
-TB-9214 front-mounting terminal block
-Printed manual

Note that the NI 9214 isothermal thermocouple module does not work with the legacy NI cDAQ-9172 chassis or any of the legacy 1-slot C Series carriers (NI USB-9162, NI ENET-9163, and NI WLS-9163).

The chassis provides rugged, modular housing for your controller (if using CompactRIO) and C Series modules. A high-performance backplane in the chassis contains the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your C Series modules. If you are using the NI CompactDAQ platform, then a Personal Computer (PC) will act as the controller of your system. However, if the CompactRIO platform is used then an embedded real-time controller will be used instead.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This device is compatible with a different programming languages depending on the platform used. If you are using the NI CompactDAQ platform then this device is compatible with LabVIEW, C/C++, Visual Basic, and .NET. However, if the CompactRIO platform is used then this device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware).
