CFP-AI-111 NI
National Instruments cFP-AI-111 Analog Input Module for Compact FieldPoint
National Instruments cFP-AI-111 (part numbers 777318-111) is a 16 channel, 16 bit analog input module designed specifically for FieldPoint and Compact FieldPoint. The channel on this model is a single ended analog input channel. Its input impedance is 100 Ω. This model also has three filter settings, 50 Hz, 60 Hz, and 500 Hz, as well as three input ranges, ± 20 mA, 4 mA to 20 mA, and 0mA to 20 mA. In addition, the update rate of the device is 3 Hz to 0.83 Hz. NI cFP-AI-111 provides integrated overvoltage protection for transients up to 2300 Vrms. This analog input module can be installed on a Compact FieldPoint backplane that is already running and powered on, as it does not interrupt the continuous operation of the bank.
The 16 input channels on the National Instruments cFP-AI-111 module share a common isolated ground reference. These input channels operate under integrated overcurrent protection set to ± 30 mA. In current measurement, the current entering the Iin terminal is considered positive, while the current leaving the terminal (Iin) is considered negative. This analog input module
The over range function included in enables the device to measure 5% beyond the nominal value of each range. Therefore, users will be able to measure ± 21 mA with a range of ± 20 mA selected. The filters provided in this device provide three settings for each channel. These filters are comb filters; Therefore, they provide notch suppression for harmonics or any fundamental frequency multiples. At the fundamental frequency, apply a suppression of 95 dB and provide at least 60 dB suppression at harmonics.
The NI device weighs 4.8 ounces and has a physical size of 4.3 x 4.3 x 3.6 inches. Its recommended operating temperature range is -40 to 70 ° C, storage temperature range is -55 to 85 ° C, non condensing humidity range is 10 to 90% RH, random and sinusoidal operating vibrations are 5 grms and 5 g respectively – both within the frequency range of 10 to 500 Hz.
National Instruments has announced the outdated status of cFP-AI-111, but Apex Waves can still purchase and repair input modules.
