CFP-AI-111 用于紧凑型 FieldPoint 的模拟输入模块

National Instruments cFP-AI-111（部件号：777318-111）是一款 16 通道、16 位模拟输入模块，专为 FieldPoint 和 Compact FieldPoint 设计。此型号上的通道是单端模拟输入通道。它的输入阻抗为 100 Ω。该型号还具有三种滤波器设置，50 Hz、60 Hz 和 500 Hz，以及三种输入范围，±20 mA、4 mA 至 20 mA 和 0mA 至 20 mA。此外，该设备的更新速率为 3 Hz 至 0.83 Hz。NI cFP-AI-111 为 高达 2,300 Vrms 的瞬态提供集成的过压保护。该模拟输入模块可以安装在已经运行并已通电的紧凑型 FieldPoint 背板上，因为它不会中断存储器的持续运行。

NI cFP-AI-111模块上的16个输入通道共享一个公共的隔离接地参考。这些输入通道在±30 mA的集成过流保护下工作。在电流测量中，进入 Iin 端子的电流被视为正电流，而离开端子的电流 （Iin） 被读取为负电流。

该模拟输入模块内置的超量程功能使该器件能够测量超出每个量程标称值 5% 的量程。因此，用户将能够在选择 ±20 mA 范围的情况下测量 ±21 mA。本设备提供的过滤器为每个通道提供三种设置。这些过滤器是梳状过滤器;因此，它们在谐波或任何基频的倍数处提供抑制陷波。在基频下，施加95 dB的抑制，在谐波上提供至少60 dB的抑制。

NI 设备重 4.8 盎司，尺寸为 4.3 x 4.3 x 3.6 英寸。在物理尺寸上。它的推荐工作温度范围为 –40 至 70 °C，存储温度范围为 –55 至 85 °C，非冷凝湿度范围为 10 至 90% RH，随机和正弦工作振动分别为 5 grms 和 5 g，频率范围为 10 至 500 Hz。

The National Instruments 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 on, as it does not interrupt the continuous operation of the memory.

The 16 input channels on the NI cFP-AI-111 module share a common isolation ground reference. These input channels operate under integrated overcurrent protection of ±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 overrange capability built into the analog input module enables the device to measure ranges up to 5% beyond 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 with this device provides three Settings for each channel. These filters are comb filters; Therefore, they provide suppression notch at harmonics or multiples of any fundamental frequency. At the fundamental frequency, 95 dB of suppression is applied, providing at least 60 dB of suppression on harmonics.

The NI device weighs 4.8 ounces and measures 4.3 x 4.3 x 3.6 inches. In physical size. 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.
