Q1: What is the primary function of the 288062-02?
It is the main card for the 3500/50M Tachometer Module. It processes signals from proximity probes or magnetic pickups to determine shaft rotational speed, rotor acceleration, and rotor direction, comparing these measurements against user-programmable alarm setpoints .
Q2: What is the difference between 288062-02 and the older 133388-02?
The 288062-02 is the M-series upgrade that succeeds the legacy 133388-02. It is not drop-in compatible — it requires the matched rear I/O board 133442-01 and M-series system firmware ≥5.30. The M-series version provides enhanced integration with System 1 diagnostic software .
Q3: Can the 288062-02 be used for overspeed protection?
No. Bently Nevada explicitly states that the 3500/50M Tachometer Module is not designed for use independently as, or as a component of, a speed control or overspeed protection system. For overspeed protection, the dedicated 3500/53 Overspeed Detection Module is required .
Q4: What companion I/O modules are required?
The 288062-02 requires a matching rear I/O module:
133442-01: Internal Terminations
133434-01: External Terminations
136703-01: Internal Barriers + Internal Terminations (hazardous area)
133450-01: TMR version with External Terminations
Q5: What firmware and software versions are required?
Adding the 3500/50M to an existing 3500 system requires:
3500/22M Module Firmware: Revision 1.70 or later
3500/01 Configuration Software: Version 4.20 or later
3500/02 Data Acquisition Software: Version 2.52 or later
3500/03 Display Software: Version 1.52 or later
3500/50M Firmware: Revision 5.30 or later
