    FAQ

    1: What is the primary function of the 133396-01 module?
    It is an overspeed detection I/O module that provides signal acquisition and protection output processing for Bently Nevada 3500 electronic overspeed detection systems on turbines and compressors.

    2: Is this module compatible with legacy 3300 series sensors?
    Yes, it supports Proximitor® eddy-current sensors (including 3300 and 3300 XL series), magnetic pickups, and passive speed sensors.

    3: Does the 3500 rack require redundant power for this module?
    Yes. As an overspeed protection safety module, the 3500 rack must be equipped with redundant power supplies to eliminate single points of failure.

    4: What is the response time of the 133396-01 overspeed detection?
    The module provides rapid response with typical detection times under 50 milliseconds for overspeed trip conditions.
