Measure millivolt, low, medium or milliampere current signals

The National Instruments cFP-AI-100 is a versatile analog input module for Compact FieldPoint and FieldPoint. The device can be used to measure voltages from the millivolt level to the high voltage level of 120 V and is suitable for applications such as fuel cell testing, battery pack monitoring and general measurement of sensors. The cFP-AI-100 can also measure 0 to 20 or 4 to 20 mA current loops from industrial sensors and transmitters.

The cFP-AI-100 measures and linearizes onboard signals to return scaling values to control or monitoring software. The module includes overrange and onboard diagnostics to ensure trouble-free installation and maintenance. To ensure reliable and accurate analog measurements, the module comes with a NIST traceable calibration certificate.

National Instruments cFP-AI-100 (Part number: 777318-100) is an 8-channel, 12-bit current and voltage analog input module. The NI cFP-AI-100 features onboard diagnostics and suspension functions to ensure simple and straightforward installation and maintenance. The module measures the signal after the on-board linearization of the signal, returning the scaling value to the user's monitoring or control application.

The analog input module has 11 input ranges and provides 250 Vrms CAT II channel continuous isolation to ground. Its 11 input ranges are: 0-1 V, 0-5 V, 0-15 V, 0-30 V, ±1 V, ±5 V, ±15 V, ±30 V, 0-20 mA, 4-20 mA, and ±20 mA. In addition, it allows hot-swappable I/O modules. All eight channels share a common grounding reference. The common ground reference is isolated from other modules installed in the FieldPoint system. The NI cFP-AI-100 can measure currents from a variety of sources: 0 to 20 mA, 4 to 20 mA, and ±20 mA. In this module, the current flows into the terminal Im, flows through a 100Ω resistor, and then leaves the circuit through the C or COM terminal. The incoming current through the Im terminal is read as positive, while the outgoing current from the terminal is read as negative. The over-range features included in the model enable it to achieve measurements slightly higher than the nominal value.

The NI cFP-AI-100 is equipped with a successive approximation 12-bit ADC (analog to digital converter). The analog input module provides a 360 Hz update rate on all channels. The module has two green LED indicators that show the power and readiness status of the device. A red indicator is also provided as an out of range indicator.

The analog input module weighs 5.1 ounces and measures 4.3 x 4.3 x 3.6 inches. In the physical dimension. Recommended operating and storage temperature ranges for NI devices are -40 °C to 70 °C and -55 °C to 85 °C, non-condensing relative humidity ranges of 10 to 90%, random and sinusoidal operating vibrations of 5 grms and 5 g, respectively. All operating frequencies range from 10 Hz to 500 Hz.

While the recommended calibration cycle for individual parts varies, most parts should be calibrated annually or biennially to ensure accuracy. If you need to calibrate the cFP-AI-100, Apex Waves provides the option. We offer high quality NIST certified calibrations through third parties with an average turnaround time of 1 to 2 weeks. When you order a cFP-AI-100 from us, you can request a basic (uncertified) internal calibration, which will calibrate the part according to the manufacturer's specifications before shipping.
