3500/25-01-01-02 Bently Nevada Enhanced Keyphasor Module

Bently Nevada 3500/25-01-01-02 Enhanced Keyphasor Module

Technical Specifications

• Manufacturer: Bently Nevada – a trusted name in machinery protection.
• Model: 3500/25-01-01-02 – Enhanced Keyphasor Module, single half-height 2-channel card.
• I/O module type: 01 = internal terminations; agency approval: 02 = ATEX/IECEx/CSA (Class 1 Zone 2).
• Power consumption: 3.2 watts typical, ensuring low energy use.
• Input signal range: +0.8 V to -21.0 V (non-isolated) or +5V to -11V (isolated). Internal limiting protects the module from over-range signals.
• Input impedance: 21.8 kΩ minimum for stable signal acquisition.
• Speed/Frequency input range: 1 to 1,200,000 cpm (0.017 to 20 kHz).
• Speed/Frequency output range: 1 to 99,999 cpm (0.017 to 1667 Hz).

Accuracy & Signal Conditioning

• Non-processed signal accuracy @ 25°C: 0.017–100 Hz: ±1 cpm; 101–500 Hz: ±8 cpm; 501–20 kHz: ±1% of cpm.
• Processed signal accuracy @ 25°C: 0.017–60 Hz: ±1 cpm; 61–150 Hz: ±8 cpm; 151–20 kHz: ±1% of cpm.
• Auto threshold: minimum signal amplitude 2 V peak-to-peak, minimum frequency 120 rpm (2 Hz).
• Manual threshold: user-selectable from 0 to -20 Vdc, minimum amplitude 500 mV peak-to-peak.
• Hysteresis: user-selectable from 0.2 to 2.5 volts for noise rejection.
• Important: passive magnetic pickups require shaft speed >200 rpm (3.3 Hz) for proper operation.

Outputs & Connectivity

• Buffered Keyphasor outputs: two coaxial connectors on the front, plus two Euro Style connectors at the rear.
• Output impedance: 504 Ω maximum for each buffered output.
• Transducer power supply: -24 Vdc, 40 mA per channel – sufficient for most probes.
• Front panel LEDs: OK (green) indicates no fault; TX/RX flashes during communication with the Rack Interface Module (RIM).

Environmental & Physical Data

• Operating temperature (standard I/O): -30°C to +65°C (-22°F to +150°F).
• Operating temperature (internal barrier I/O): 0°C to +65°C (32°F to +150°F).
• Storage temperature: -40°C to +85°C (-40°F to +185°F).
• Humidity: 95% non-condensing, suitable for harsh environments.
• Main module dimensions: 119.9 x 24.4 x 256.5 mm (H x W x D).

Installation & Ordering Notes

• This 3500/25-01-01-02 uses internal termination I/O modules – do not use external termination blocks.
• If you need external terminations, order the blocks and cables separately.
• Consult a qualified Bently Nevada representative for advanced signal processing applications.
• Warning: this module carries ATEX/IECEx/CSA certification for Zone 2 hazardous areas – follow all safety instructions.

Frequently Asked Questions (FAQ)

• Q: Is this module brand new or used?
  A: This 3500/25-01-01-02 is brand new, factory-sealed, and fully tested by Bently Nevada.
• Q: Can I use this module with a magnetic pickup at very low speeds?
  A: Yes, but the shaft must rotate above 200 rpm (3.3 Hz) for reliable signal detection.
• Q: What is the difference between auto and manual threshold?
  A: Auto threshold triggers at 2 V peak-to-peak; manual threshold lets you set a level from 0 to -20 Vdc.
• Q: Does this module support isolated inputs?
  A: Yes, if you choose the isolated I/O module option, the input range becomes +5V to -11V.
• Q: How many channels does this module provide?
  A: This single half-height card offers two independent Keyphasor channels.
