Features:
- Exact PWA103928-02 identity for the TDXnet Keyphasor input function.
- Supports speed and phase-reference acquisition used by synchronous machinery data.
- Board revision, connector position and software configuration must match the installed 2155/00 assembly.
PWA103928-02 provides the Keyphasor input function within the Bently Nevada TDXnet architecture. The TDXnet system accepts four Keyphasor inputs over a documented range of 60 to 60,000 rpm and can select a real or simulated backup source through software.
The Keyphasor reference is used to organize synchronous vibration information, shaft speed and phase during steady-state and startup/shutdown data collection. Replace this board only after recording the installed revision, connectors, mainframe position and configuration, then verify stable speed and phase data after commissioning.
The PWA103928-02 Bently Nevada TDXnet Keyphasor Input Board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada PWA103928-02 documentation and reference links.
Important Notice: No qualified exact-model manufacturer PDF was confirmed, so the first link uses the internal 2155 Series page. Confirm the complete part number, revision, installed system and required accessories before replacement.
The PWA103928-02 board provides the TDXnet speed and phase reference used to organize synchronous vibration measurements and startup/shutdown data. The installed transducer source, threshold behavior and backup selection must be retained.
Use the board only in the documented Bently Nevada 2155/00 TDXnet assembly. Record the board revision, mainframe position, connected Keyphasor circuits and software settings before removal.
After replacement, verify stable rpm and phase information, correct real or simulated backup-source selection and the expected synchronous plots through the connected machinery-management software.
