NI SCXI-1104C | Voltage Input Module

Description

Functional Features Multi-channel Input: It has 8 differential input channels, which can condition multiple analog signals simultaneously. It is suitable for application scenarios that require the collection of multiple signal sources, such as multi-channel temperature, pressure, or strain measurement, etc. Signal Isolation: It provides electrical isolation from the channel to the ground, and the isolation voltage can generally reach up to 500Vrms. This effectively prevents signal interference and electrical noise, protects the safety of measurement equipment and personnel, and improves the measurement accuracy. Configurable Gain: The gain range is usually selectable from 1 to 1000. Users can flexibly set an appropriate gain value according to the magnitude of the input signal to optimize the measurement resolution and dynamic range. Low-pass Filtering: It has a built-in low-pass filter, and different cut-off frequencies (such as 10Hz, 100Hz, 1kHz, etc.) can be set. It can effectively suppress high-frequency noise, making the collected signals smoother and more accurate. Software Programmable: It supports programming control through software such as NI's LabVIEW, which facilitates users to configure parameters and customize functions according to specific measurement requirements, and realize automated data collection and processing.

Technical Parameters Input Range: It supports a variety of input ranges, such as ±10V, ±1V, ±0.1V, etc., to adapt to the output signals of different types of sensors. Gain Accuracy: The gain accuracy is relatively high, and it can maintain good linearity under different gain settings to ensure the accuracy of the measurement results. Common-mode Rejection Ratio (CMRR): The typical value is generally above 100dB, which can effectively suppress common-mode signal interference and improve the anti-interference ability of the measurement system. Sampling Rate: When used in conjunction with a compatible NI data acquisition card, a relatively high sampling rate can be achieved to meet the acquisition requirements of rapidly changing signals. Operating Temperature Range: Generally, it is from 0°C to 55°C, and it can work stably under certain ambient temperature conditions.

Application Areas Industrial Monitoring and Control: It is used to monitor various physical quantities in the industrial production process, such as temperature, pressure, flow rate, vibration, etc., providing data support for the optimization of the production process and fault diagnosis. Scientific Research: In a laboratory environment, it can accurately collect and analyze various experimental data. For example, in material mechanics experiments, it measures parameters such as strain and stress, and in electronic circuit experiments, it collects voltage and current signals, etc. Automotive Testing: It is used for automotive performance testing. For example, it measures parameters such as the engine's rotational speed, torque, temperature, as well as the acceleration and braking distance during the vehicle's driving process, helping automotive engineers to optimize the design and improve product quality. Aerospace: In the aerospace field, it can condition and collect the signals of various sensors of the aircraft, such as the signals of pressure sensors, temperature sensors, displacement sensors, etc., providing an important basis for the performance evaluation and fault diagnosis of the aircraft.
