        • System-Level Protection: Provides power-up inhibition, disabling alarms for the first 2 seconds after power-on or voltage instability, effectively preventing false triggering.
        • Status Monitoring Efficiency: The front panel features 7 internal voltage indicator lights (e.g., +VRH, -VT) and a green SUPPLIES OK LED, facilitating quick diagnosis of the frame's power status by maintenance personnel.
        • Alarm Management: Supports a "Trip Multiply" function, temporarily increasing alarm thresholds by a preset ratio under special operating conditions such as machine startup, avoiding unnecessary downtime.
        • Rotating Machinery Protection: Provides isolated power, terminal connections, and signal conditioning for up to 4 proximity probe keyphasors, supporting speed monitoring from 60 to 30,000 rpm.
        • Industrial Integrated Monitoring: Suitable for asset status management in fields such as power (steam turbines, generators) and petrochemicals (compressors), enabling vibration and displacement monitoring in conjunction with the 3300 XL series sensors.
        • Legacy System Upgrade: As the core of the SDI/DDI system, it allows older 3300 frames to be connected to modern System 1 machine management software via a serial interface.
        • Serial Data Interface (SDI/DDI): RS232: Up to 19.2 kbaud baud, maximum transmission distance 30 meters, suitable for short-distance connection to the main controller; RS422: Up to 38.4 kbaud baud (DDI mode), maximum transmission distance up to 1200 meters, supports daisy-chaining of multiple frames.
        • External Control Interface: Backplane terminals provide dry contact connections for "Rack Inhibit," "Alarm Reset," and "Multiplier Trigger."
        • Signal output: The front panel provides 4 coaxial cable interfaces (BNC) to output buffered phase signals, which are convenient for portable instruments in the field (such as vibration analyzers) to directly acquire the original waveform.
