CFP-AI-111 模拟输入模块 单端模拟输入通道

【产品详情】

National Instruments cFP-AI-111（部件号：777318-111）专为 FieldPoint 和 Compact FieldPoint 而设计，是一款 16 通道、16 位模拟输入模块。此型号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，该器件的更新速率为 3 Hz 至 0.83 Hz。NI cFP-AI-111 为 高达 2,300 Vrms 的瞬变提供集成过压保护。该模拟输入模块可以安装在已经运行并通电的紧凑型 FieldPoint 背板上，因为它不会中断银行的持续运营。

NI cFP-AI-111 模块上的 16 个输入通道共享一个公共隔离接地参考。这些输入通道在设置为±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值，而离开端子 （Iin） 的电流被读取为负值。

该模拟输入模块中集成的超量程功能使该器件能够测量超出每个量程标称值 5% 的测量值。因此，用户将能够在选择 ±20 mA 量程的情况下测量 ±21 mA。该器件中提供的滤波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，在谐波时提供至少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。在物理维度上。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，频率范围均为 10 至 500 Hz。

【英文介绍】

Designed for FieldPoint and Compact FieldPoint, the National Instruments cFP-AI-111 (Part number: 777318-111) is a 16-channel, 16-bit analog input module. The channel for this model is a single-ended analog input channel. Its input impedance is 100 Ω. The model also has three filter Settings: 50 Hz, 60 Hz, and 500 Hz, and 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 will not interrupt the bank's ongoing operations.

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 set to ±30 mA. In current measurement, the current entering the Iin terminal is treated as 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 measurements that exceed 5% of the nominal value of each range. As a result, users will be able to measure ±21 mA with a ±20 mA range selected. The filter provided in the 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 at harmonics.

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, a storage temperature range of -55 to 85 °C, a non-condensing humidity range of 10 to 90% RH, random and sinusoidal operating vibrations of 5 grms and 5 g respectively, and a frequency range of 10 to 500 Hz for both.
