Model: CFP-AI-111
Category: Analog input module for compact FieldPoint
The CFP-AI-111 (Part number: 777318-111) is a 16-channel, 16-bit analog input module designed for FieldPoint and Compact FieldPoint. The channels on this model are single-ended analog input channels. Its input impedance is 100 Ω. The model also features 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 device has an update rate of 3 Hz to 0.83 Hz. The NI cFP-AI-111 provides integrated overvoltage protection for transients up to 2,300 Vrms. The analog input module can be installed on a compact FieldPoint backplane that is already running and powered, as it will 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 and are set to ±30 mA. In current measurement, the current entering the Iin terminal is considered positive, while the current leaving the terminal (Iin) is read as negative.
The integrated overrange function in this analog input module enables the device to measure more than 5% of the nominal value of each range. As a result, users will be able to measure ±21 mA with the choice of ±20 mA range. The filter provided in this device provides three Settings for each channel. These filters are comb filters; Therefore, they provide suppression gaps at harmonics or multiples of any fundamental frequency. At the fundamental frequency, a suppression of 95 dB is applied, and at the harmonics, a suppression of at least 60 dB is provided.
The NI device weighs 4.8 ounces and measures 4.3 x 4.3 x 3.6 inches. In the physical dimension. It has a recommended operating temperature range of -40 to 70 °C, storage temperature range of -55 to 85 °C, non-condensing humidity range of 10 to 90% RH, random and sinusoidal operating vibration of 5 grms and 5 g respectively, and frequency range of 10 to 500 Hz.cFP-AI-111
