SCXI-1104C

Description

The National Instruments SCXI-1104C Voltage Input Module, with part numbers 776572-04C and 183087H-05, is designed for signal conditioning of higher voltage signals across 32 differential channels and features a 10 kHz cut-off frequency filter. Compatibility with ribbon-cabled multichassis SCXI systems is facilitated through the SCXI-1346 multichassis adapter, and module detection can be either automatic or manually configured.

While the module’s analog outputs are short-circuit protected, they are not safeguarded against overvoltage; thus, care must be taken to prevent damage by external voltages. The SCXI-1104C requires a recommended warm-up time of 20 minutes and operates within a temperature range of 0 to 50 °C.

Regular calibration, at least annually or following any operation outside the normal temperature range, is essential for maintaining accuracy and should be performed using a multiranging 8.5 digital multimeter. The module operates using NI-DAQ version 6.5.1 or higher software drivers and is compatible with various application development environments, including LabVIEW, BridgeVIEW, LabWindows/CVI, Visual Basic (ComponentWorks), C, C++, VirtualBench, and Measure.

Question 1: What precautions should be taken when using the National Instruments SCXI-1104C Voltage Input Module to prevent damage by external voltages, given that its analog outputs are short-circuit protected but not overvoltage protected?
Answer 1: The National Instruments SCXI-1104C Voltage Input Module lacks protection against overvoltage, and it is recommended to have a warm-up time of 20 minutes for optimal operation.

Question 2: What precautions should be taken to prevent damage from overvoltage to the analog outputs of the National Instruments SCXI-1104C Voltage Input Module, considering they are short-circuit protected but not overvoltage protected?
Answer 2: To prevent damage from overvoltage to the analog outputs of the National Instruments SCXI-1104C Voltage Input Module, it is essential to ensure that the connected external voltages do not exceed the specified limits of the module, as the outputs are short-circuit protected but lack overvoltage protection.

Question 3: What type of external voltage protection is the National Instruments SCXI-1104C Voltage Input Module lacking, and what is the recommended warm-up time for optimal operation?
Answer 3: To maintain the accuracy of the National Instruments SCXI-1104C Voltage Input Module, it should be calibrated at least annually or after any use outside of its normal operating temperature range of 0 to 50 °C, using a multiranging 8.5 digital multimeter, and it must operate with NI-DAQ version 6.5.1 or higher software drivers, ensuring compatibility with its designated application development environments.

Question 4: What procedures should be followed to maintain the accuracy of the National Instruments SCXI-1104C Voltage Input Module, considering its need for regular calibration and specific operating software versions?
Answer 4: When using the National Instruments SCXI-1104C Voltage Input Module, it is important to carefully monitor and control the external voltages applied to the module to ensure they do not exceed its specified limits, as the module’s analog outputs are short-circuit protected but lack overvoltage protection.

Question 5: What is the recommended warm-up time for the National Instruments SCXI-1104C Voltage Input Module, and within which temperature range does it operate?
Answer 5: The recommended warm-up time for the National Instruments SCXI-1104C Voltage Input Module is 20 minutes, and it operates within a temperature range of 0 to 50 °C.
