The NI 9206 C Series module for use with any CompactDAQ or CompactRIO system features 16 differential analog inputs, 16-bit resolution, and a maximum sampling rate of 250 kS/s. Each channel has programmable input ranges of ±200 mV, ±1 V, ±5 V, and ±10 V. To protect against signal transients, the NI 9206 includes ±30 V of overvoltage protection between input channels and common (COM). In addition, the NI 9206 also includes a channelto-earth-ground double isolation barrier for safety, noise immunity, and high common-mode voltage range.
The NI 9206 is rated for 1,000 Vrms transient overvoltage protection. The NI 9206 provides up to 600 VDC (400 VDC in Europe) channel-to-earth ground isolation, making the module ideal for accurately monitoring large fuel cell and battery stacks. Though each bank of measured cells can be up to 600 V from earth ground, each channel of the NI 9206 must remain within 10 V of the module COM.
