I am selling one National Instruments NI 9421 module. The 9421 module has an MSRP of $99. This unit was installed in an enclosure for data acquisition, but the build was never completed. The contractor that was doing this work was released before their equipment was ever finished (as can be seen in the pictures). This is why the 9421 are listed as NEW as it WAS NEVER POWERED ON and comes with none of the original packaging or paperwork. I have powered on the entire cRIO chassis and all modules shown and everything powers up fine. This listing is for one NI 9421 module and not the other National Instrument modules or cRIO chassis shown. I am also selling the other modules and cRIO chassis seen in the photos. They are: 1 - NI cRIO-9074 Integrated 400 MHz Real-Time Controller (151515203040) 4 - NI 9203 ±20 mA, Current Analog Input, 200 kS/s, 8 Ch Module (151515227642) 1 - NI 9219 Analog Input, 24-Bit, 100 S/s/ch, 4 Ch Module (151516404587) 1 - NI 9472 8-Chan 24 V Logic, 100 µs, Sourcing Digital Output (151516440071) 1 - NI 9871 4-Port, RS485/RS422 Serial Interface Module cRIO (151516467700) 1 - PS-15 Power Supply 5 A, 24 VDC cRIO (151516478862) Please check out these other listings. An overview of the NI 9421 module is listed below from the National Instrument website: The NI 9421 is an 8-channel, 100 µs sinking digital input module for any NI CompactDAQ or CompactRIO chassis. Each channel is compatible with 24 V signals and features transient overvoltage protection of 2,300 Vrms between the input channels and earth ground. Each channel also has an LED that indicates the state of that channel. The NI 9421 works with industrial logic levels and signals to directly connect to a wide array of industrial switches, transducers, and devices. You can choose from two connector options for the NI 9421: a 10-position screw-terminal connector and a 25-position D-SUB connector. This industry-standard 25-position D-SUB connector provides for low-cost cabling to a wide variety of accessories from NI or other vendors. Some vendors with custom D-SUB cable fabrication services can deliver cables with pinouts that match your exact application needs.
