The CFP-AI-100 is an analog input module manufactured by National Instruments for Compact 

FieldPoint and FieldPoint systems. Here are some of its features and parameters:

• Features:

• Versatility: 8 channels to measure voltage or current signals, from millivolts to 120V high voltage levels, as well as 0-20 or 4-20 mA current loops for industrial sensors and transmitters. For example, in battery pack monitoring, the voltage of multiple batteries can be monitored simultaneously; In industrial automation, the current signal of the sensor can be accurately measured.

• High precision: 12-bit resolution, can achieve high precision analog signal measurement, can accurately capture small signal changes, suitable for high measurement accuracy requirements, such as precision instrument measurement and control.

• Easy to use: with software configurable input range and Hot PnP (plug and play) operation function, convenient for users to set and quickly deploy according to actual needs, reduce the complex configuration process, improve the use efficiency.

• Diagnostic function: The onboard diagnostic function ensures trouble-free installation and maintenance, and can quickly locate faults when problems occur, facilitate timely troubleshooting, and reduce equipment downtime and maintenance costs.

• Calibration Assurance: With NIST traceable calibration certificates, measurement accuracy and reliability are guaranteed, and users can regularly calibrate to maintain high precision measurements.

• Technical parameters:

• Input range: including 0-1V, 0-5V, 0-15V, 0-30V, ±1V, ±5V, ±15V, ±30V, 0-20mA, 4-20MA, ±20mA and other 11 different input ranges, to meet a variety of signal measurement needs.

• Isolation performance: Provides 250 VRMS Cat II channel to ground isolation, enhances the anti-interference ability of the signal, ensures the stability of the measurement, and can work stably in the industrial environment with certain interference.

• Update rate: The update rate of all channels is 360Hz, which can timely obtain the change of the signal and accurately measure the rapidly changing signal.

• Indicators: There are two green LED indicators to show the power and device readiness status, and a red overrange indicator to facilitate the user to intuitively understand the module's working status and signal is out of range.

• Physical size: Weighing just 5.1 ounces (about 144.59 grams) and measuring 4.3 x 4.3 x 3.6 inches (about 10.92 x 10.92 x 9.14 cm), it is small and light enough to fit into devices with limited space.

• Working environment: working temperature range is -40 °C to 70°C, storage temperature range is -55 °C to 85°C, relative humidity range is 10% to 90% (non-condensing), can adapt to more harsh working environment; In the frequency range of 10Hz to 500Hz, it can withstand 5g random and sinusoidal operating vibration, ensuring stability under different working conditions.

CFP-AI-100 modules are commonly used in test and measurement, industrial automation, data acquisition, scientific research, control systems and other fields. For example, in the quality inspection of the automated production line, the analog signal of the sensor is collected to determine whether the product is qualified; In scientific research experiments, various simulated data during the experiment are accurately measured.
