NI CFP-AI-100 technical industrial control analysis:high-precision analog input module

1.Product Overview

The NI CFP-AI-100 is an 8-channel analog input module from National Instruments(NI)designed for Compact FieldPoint and FieldPoint systems,supporting high-precision acquisition of voltage(0-30 V)and current(0-20 mA/4-20 mA/±20 mA)signals.Its core advantages include 12-bit resolution,250 Vrms CAT II isolation,hot-swap function,and over-range alarm.It is suitable for industrial automation,data acquisition,scientific research and experiments and is particularly outstanding in environments with dangerous voltages.

2.Core functions and technical characteristics

1.Signal measurement and isolation

Multi-range input:supports 11 input ranges(such as 0-1 V,±30 V,4-20 mA,etc.),which can be configured software to meet different sensor needs.

High precision isolation:

Channel-to-ground isolation:250 Vrms CAT II(passed 2300 Vrms 1 minute pressure resistance test),complying with IEC 61010-1 double insulation standard.

Common grounding reference:All channels share the same grounding,isolate from other modules,and avoid signal interference.

2.High-performance hardware

ADC conversion:adopts a successive approximation 12-bit ADC,providing a 360 Hz update rate(2.8 ms sampling period per channel).

Hot-swap design:supports online replacement of modules to reduce system downtime.

3.Diagnosis and alarm

Over-range detection:It can measure signals exceeding the nominal range by 20%(such as±5 V range supports±6 V measurements),avoiding data abnormalities due to noise or equipment errors.

LED indicator:

Green LED displays power and ready status;

The red LED indicates that the signal exceeds the limit or is faulty.
