NI 9214/NI9214/9214采集卡/數據采集卡

概述

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).
