Description

NI  SCXI-1104C  high-performance voltage input module

Channel parameters: It features 32 differential analog input channels, which can multiplex multiple input signals to a single module output to drive the input channels of the data acquisition device and increase the number of channels in the data acquisition system.
Signal range: The signal range that can be processed is ±42VAC or ±60VDC, suitable for the conditioning of medium-voltage signals.
Filtering features: Each channel is equipped with a three-pole low-pass filter with a cut-off frequency of 10kHz, which can effectively suppress high-frequency noise, retain signals within a specific frequency range, and better handle time-varying medium-voltage signals.

Attenuator: Each channel has a 10-division attenuator stage before the amplifier, which can preprocess the input signal to meet the requirements of subsequent processing and also protect the module from overvoltage.
Sampling rate: The maximum sampling rate can reach 333ks/s, enabling rapid signal acquisition and meeting the requirements of some application scenarios that have high demands for data acquisition speed.
Connector type: The front end is a 96-pin male DIN C connector, and the rear end is a 50-pin male ribbon cable connector.
Operating temperature: The recommended operating temperature range is 0℃ to 50℃.

Module calibration: Calibration can be carried out by applying precise voltage and/or grounding to the channel input. It is recommended to calibrate at least once a year or after use beyond the specified temperature range.
Software driver: A NI-DAQ version 6.5.1 or higher software driver is required, which can be used in various application development environments such as LabVIEW, LabWindows/CVI.
