Description
The part number 777966-40 refers to a specific product within the SCXI & Legacy category, known as the SCXI-1540. This item is a National Instruments SCXI-1540 LVDT Input Module, designed to interface with various types of sensors such as LVDTs, RVDTs, and Resolvers. It supports both 4 and 5-wire connections for LVDTs and RVDTs, ensuring versatility in its application.
This module boasts an impressive scanning rate of up to 333 kS/s, and it features the ability to perform random scanning of selected channels. This makes it highly efficient for data acquisition tasks. One of the standout features of the SCXI-1540 is its autocalibration capability, which can be executed through NI-DAQ or LabVIEW VI without the need for external hardware, simplifying the calibration process significantly.
Importantly, calibration data is stored directly on EEPROMs on the module, ensuring that calibration settings are preserved even when the module is powered down or removed from its setup. Configuration of the module can be handled through Measurement & Automation Explorer (MAX) or NI-DAQ function calls, providing flexibility in how it is integrated into a system.
Another critical feature is its channel synchronization, which allows any quantity of channels to be synchronized to the same frequency, enhancing the accuracy and reliability of measurements. Despite its obsolete status, it has been announced that this module is still available for purchase and repairs through Apex Waves, ensuring that users can continue to rely on this high-quality input module for their data acquisition needs.
