The National Instruments 9205 is a C Series module, for use with NI CompactDAQ and CompactRIO chassis. The NI 9205 features 32 single-ended or 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, 5, and 10 V. To protect against signal transients, the NI 9205 includes up to 60 V of overvoltage protection between input channels and common (COM). In addition, the NI 9205 also includes a channel-to-earth-ground double isolation barrier for safety, noise immunity, and high common-mode voltage range. It is rated for 1,000 Vrms transient overvoltage protection.
There are two connector options for the NI 9205; a 36-position spring terminal connector for direct connectivity or a 37-position D-Sub connector. To add strain relief and high-voltage protection to the 36-position terminal of the NI 9205, NI recommends the NI 9940 strain-relief connector accessory.
The NI 9205 with D-Sub option has an industry-standard 37-position D-Sub connector that provides a low-cost cabling option to a wide variety of accessories available from NI or other vendors. A number of vendors who provide custom D-Sub cable fabrication services, can provide cables with a pin-out that matches your exact application needs. The NI 9933 (or other 37-pin D-Sub connector) is required for use with the NI 9205 with D-Sub. The NI 9933 includes a screw-terminal connector with strain relief as well as a D-Sub solder cup backshell for creating custom cable assemblies.
