Description
Bently Nevada 3300/05‑24‑00‑00
- Technical & Performance Parameters:
- Contact type: Isolated dry contact
- Rated contact capacity: 250 V AC / 30 V DC
- Operating mode: Jumper configurable normally‑energized / normally‑de‑energized
- Power supply: Powered by 3300 rack backplane
- Operating temperature: ‑40 °C ~ +70 °C
- Material Composition: Metal front panel with relay‑status LED indicators; PCB equipped with industrial electromagnetic relays, optocoupler isolation circuit and bus‑signal receiving circuit; metal locking latch for rack installation.
- Structural Characteristics: Single‑width plug‑in module for 3300 rack. Installs behind corresponding monitor module slot. Rear edge connector connects rack alarm bus and power supply. External alarm wiring connects to terminal points of module rear side. Supports hot‑swap inside rack.
- Working Principle: Receives alarm level signal from 3300 internal alarm bus. After optocoupler isolation, drives corresponding electromagnetic relay coil. Relay dry‑contact changes status when alarm condition occurs, sending hard‑wired alarm signal to external protection interlock circuit. Front‑panel LED reflects real‑time relay actuation state.
- Application Scenarios: Matches various 3300 series monitoring modules. Used for turbine overspeed alarm, vibration alert / danger interlock, thrust position protection trip signal output. Applied in power plant, petrochemical plant rotating machinery protection interlock loop.
- Installation Requirements: Install in designated slot position behind function monitor module inside 3300 rack. Configure relay working‑mode jumpers before power‑on. External interlock wiring shall comply with site safety specification. Do not exceed rated voltage and current limit of relay contacts. Guarantee rack heat dissipation environment.
- Usage Notes: Confirm normally‑energized / normally‑de‑energized setting matches safety interlock requirement. Regularly inspect relay contact aging condition. Do not overload contact capacity. When replacing module, keep jumper configuration consistent with original setting.
