Description
The Advantech iDAQ-841 is a high-performance 8-channel analog input module designed for precise, high-speed data acquisition in industrial and test applications. Featuring true simultaneous sampling at up to 1 MS/s per channel with 16-bit resolution, the iDAQ-841 ensures accurate capture of fast-changing signals without phase distortion.
This module supports both voltage and current measurements with software-configurable input ranges, making it highly flexible for mixed-signal environments. Integrated isolation protection, configurable low-pass filtering, and advanced triggering capabilities provide reliable operation in electrically noisy industrial conditions. Compact and rugged, the iDAQ-841 is well-suited for automated test systems, condition monitoring, and precision measurement platforms.
