Description
Bently Nevada 3300/05‑26‑00‑00
- Technical & Performance Parameters:
- Contact form: Isolated dry‑contact output
- Contact rating: 250 V AC / 30 V DC maximum
- Power source: 3300 rack backplane power supply
- Operating temperature: ‑40 °C ~ +70 °C
- Signal source: 3300 system internal alarm bus
- Material Composition: Aluminum front panel with LED indicators; PCB assembled with high‑reliability industrial relays, isolation optocouplers, bus‑signal processing circuit; metal locking hardware for rack mounting.
- Structural Characteristics: Single‑width plug‑in unit for 3300 rack chassis. Installs behind corresponding measurement monitor module. Rear edge connector links rack backplane alarm bus. External field wiring terminates at rear‑side terminals. Supports hot‑swap inside rack.
- Working Principle: Monitors alarm bus status signals sent by measurement modules inside rack. Triggers corresponding electromagnetic relay after signal isolation processing. Relay contact state changes to output hard‑wired alarm signal for external safety interlock and trip circuit. Front‑panel LED displays relay actuation condition.
- Application Scenarios: Matches vibration, speed, position monitoring modules in 3300 TSI system. Used for turbine, compressor, generator alarm interlock and trip signal output. Suitable for power, petrochemical heavy‑duty rotating equipment protection loops with special ordering requirements.
- Installation Requirements: Install in dedicated slot behind monitor module inside 3300 rack. Verify internal jumper configuration matches project requirement. External wiring must not exceed relay contact rated load. Keep signal cables separate from high‑power cables. Ensure good ventilation of rack cabinet.
- Usage Notes: Record original jumper setting before module replacement. Strictly avoid overloading relay contacts. Regular visual check for relay‑status LED. Do not modify internal circuit components arbitrarily. Confirm interlock logic correctness after module replacement.
