Overview

nnnn

The NI 9206 Measurement System measures 32 voltage channels at 250 kS/s with 16-bit resolution, sending data to a host PC over

nnnn

USB, Ethernet or 802.11 Wi-Fi.

nnnn

Measurement Bundle Overview

nnnn

The hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 W-Fi chassis and one of

nnnn

the over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed

nnnn

measurements.

nnnn

Chassis

nnnn

The chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 W-Fi bus.

nnnn

Additionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.

nnnn

Module

nnnn

The NI 9206, for use with NI CompactDAQ and CompactRIO chassis, features 16 differential analog inputs, 16-bit resolution, and a

nnnn

maximum sampling rate of 250 kS/s. Each NI 9206 channel has programmable input ranges of ±200 mV, ±1 V, ±5 V, and ±10 V.

nnnn

The NI 9206 provides up to 600 VDC (400 VDC in Europe) bank isolation from earth ground, which makes the module ideal for

nnnn

accurately monitoring large fuel cell and battery stacks. While each bank of measured cells can be up to 600 V from earth ground,

nnnn

each channel of the NI 9206 must remain within 10 V of the module COM. By referencing the module COM to the middle of the NI

nnnn

9206 bank, you can measure 16 consecutive cells.

nnnn

The NI 9206 comes with the NI 9941 connector accessory, which includes a spring terminal connector and backshell to provide strain

nnnn

relief for taking high-voltage measurements.

nnnn

Note: The NI 9206 should not be connected to MAINs CAT II, III, or IV circuits. It is a UL-recognized component that must be installed

nnnn

in a suitably UL-rated enclosure such as the NI 9917 or NI 9918 industrial enclosures. See the product manual for proper installation

nnnn

and restrictions for safe use of the NI 9206 and explanation of measurement categories (CAT).
