BENTLY 3500/33 149986-01

• Relay Lifespan: 100,000 operations at 5 A, 24 VDC/240 VAC.
• Operating Modes: Each group of 4 channels supports configurable normally open (NO) or normally closed (NC) states.
• Alarm Logic: Supports AND/OR programming via 3500 Rack Configuration Software, enabling complex conditions based on monitoring channel inputs (e.g., Alert/Danger states, non-OK status).
• Indicators:
  • OK LED: Confirms normal module operation.
  • TX/RX LED: Indicates communication activity.
  • Channel Alarm LED: Signals per-channel alerts.
• Environmental Tolerance:
  • Operating Temperature: -30°C to +65°C.
  • Storage Temperature: -40°C to +85°C.
  • Humidity: 95% non-condensing.
• Physical Dimensions:
  • Module: 241 mm (H) × 24.4 mm (W) × 242 mm (D).
  • I/O Module: 241 mm (H) × 24.4 mm (W) × 99.1 mm (D).
• Weight: 0.7 kg (module), 0.4 kg (I/O module).

Key Features

• High-Density Outputs: 16 relays in a single module optimize rack space and reduce wiring complexity.
• Flexible Alarm Configuration: Programmable logic allows customization of报警 conditions (e.g., combining inputs from vibration, temperature, or pressure sensors).
• Voting Logic Support: Configurable “2 out of 3” or similar voting mechanisms enhance system reliability by minimizing false alarms.
• Low-Current Option: Gold-plated contacts (optional) enable switching of low-power signals (e.g., PLC inputs).
• Industrial-Grade Design: Withstands harsh environments with electromagnetic compatibility (EMC) compliance.

Application Scenarios

• Machinery Protection:
  • Rotating Equipment: Monitors turbines, compressors, and pumps for vibration, temperature, or speed anomalies, triggering shutdowns to prevent damage.
  • Power Generation: Integrates with turbine control systems to enforce safety protocols during over-speed or over-temperature events.
• Process Control:
  • Chemical Plants: Transmits alarm signals to distributed control systems (DCS) for process optimization.
  • Steel Mills: Controls cooling systems based on equipment temperature feedback.
• Safety Systems:
  • Emergency Stop Circuits: Acts as a redundant layer in safety instrumented systems (SIS) for SIL 2/3 compliance.
  • Fire & Gas Detection: Interfaces with suppression systems to initiate actions on sensor triggers.
• Infrastructure Monitoring:
  • Railway Signaling: Manages track switch operations with sub-second response times.
  • Water Treatment: Regulates pump speeds based on flow rate measurements.

Advantages

• Cost Efficiency: Reduces capital expenditure by consolidating relay functions into one module.
• Scalability: Seamlessly expands with additional 3500 series modules (e.g., vibration monitors, power supplies).
• Global Support: Backed by ABB/Bently Nevada’s service network, offering 24/7 technical assistance and long-term spare part availability.
• Interoperability: Compatible with legacy systems (e.g., Modbus RTU) and modern protocols (e.g., OPC UA).
