Configured specifically for integration within the 3500 machinery protection rack, the Bently Nevada 3500/50-02-00 processes highly precise speed and phase measurement signals to safeguard rotating machinery. By accepting up to two independent transducer signals, this Tachometer Module tracks rotational speed, phase angles, and acceleration criteria. The 3500/50-02-00 configuration features the specialized I/O module designed for external terminations, streamlining complex cabinet cabling architectures while offering high input impedance and robust signal conditioning in demanding industrial environments.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Bently Nevada |
| Part Number / SKU | 3500/50-02-00 |
| Series | 3500 Machinery Protection System |
| Module Type | Tachometer Module |
| I/O Module Type | 02 = I/O Module with External Terminations |
| Agency Approval Option | 00 = None |
| Input Channels | 2 channels (proximity probes or magnetic pickups) |
| Input Signal Range | +10.0 V to -24.0 V (limited internally) |
| Input Impedance | 20 k ohms (standard) / 40 k ohms (TMR) / 7.15 k ohms (Internal Barrier) |
| Power Consumption | 5.8 watts, typical |
| Country of Origin | United States |
| Shipping Weight (Calculated) | 3.0 kg |
While the 3500/50-02-00 provides external termination support, users requiring internal termination blocks should verify suitability with the 3500/50-01-XX variations. Always cross-reference the 3500 firmware revision level within the Rack Configuration Software to guarantee correct driver mapping and module register recognition prior to physical installation.
When pairing this tachometer module with magnetic pickups, be aware that voltage amplitude scales downward at lower shaft speeds. Ensure your minimum speed setpoints and auto-threshold configurations in the software are adjusted above the transducer's low-voltage noise ceiling. For High Availability configurations, implementing TMR (Triple Modular Redundant) input impedance matching (40 k ohms) prevents single-point failure propagation across standard parallel connections.
When routing external terminations, always deploy high-quality shielded twisted-pair (STP) cabling for all sensor inputs. Magnetic pickup lines are exceptionally sensitive to ambient EMI. Ensure the shield drain wire is terminated strictly at the designated instrument earth ground on the 3500 rack chassis and isolated at the machine junction box to eliminate parasitic ground loops.
Ensure total rack power de-energization and confirm all residual capacitive and static energy has been safely bled to earth before handling. Inserting or removing modules while the rack is powered can cause catastrophic backplane communication failures or module transceiver damage.
