Q1: What is the primary function of the 3500/50M-01-00?
It is a 2-channel Tachometer Module that accepts input from proximity probes or magnetic pickups to determine shaft rotational speed, rotor acceleration, and rotor direction. It compares these measurements against user-programmable alarm setpoints and generates alarms when thresholds are violated. It can also supply conditioned Keyphasor signals to the 3500 rack backplane for use by other monitoring modules .
Q2: Can the 3500/50M be used for overspeed protection?
No. Bently Nevada explicitly states that Tachometer Modules are 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 .
Q3: What is the difference between the 3500/50 and the 3500/50M?
The 3500/50M is the M-series version that provides enhanced integration with System 1 diagnostic software. The standard 3500/50 is the non-M version. Both share the same fundamental speed monitoring capabilities, but the M-series offers expanded diagnostic and data collection features .
Q4: What companion I/O modules are required?
The 288062-02 main card requires a matching rear I/O module:
133442-01: Internal Terminations (this configuration)
133434-01: External Terminations
136703-01: Internal Barriers + Internal Terminations (hazardous area)
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
