In addition, the NI 9206 also includes a channel-to-earth-ground double isolation barrier for safety, noise immunity, and high common-modevoltage range.

2 The NI 9206 is rated for 1,000 Vrms transient overvoltage 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. Thougheach bank of measured cells can be up to 600 V from earth ground, each channel of theNI 9206 must remain within 10 V of the module COM.
