Description

BENTLY 1900/65A-00-00-02-00-01 Compact Vibration Monitoring Module

1. Product Description

• Dual-Channel Monitoring: Supports two independent input channels for simultaneous measurement of vibration velocity or acceleration, compatible with IEPE accelerometers or magnetoelectric velocity sensors.
• Real-Time Alarm Outputs: Features 2 analog outputs (4–20 mA) for continuous data transmission and configurable alarm relays to trigger alerts when vibration levels exceed preset thresholds.
• Rugged Compact Design: Operates in harsh environments with a wide temperature range (-40°C to +85°C) and resistance to electromagnetic interference (EMI), suitable for challenging industrial settings.
• Easy Integration: Designed for plug-and-play installation with PLC/DCS systems, offering straightforward configuration via front-panel dip switches or optional software tools.

6. Selection Recommendations

• Equipment Size: Choose the 1900/65A-00-00-02-00-01 for machinery with shaft speeds up to 10,000 RPM (e.g., pumps, fans)；consider higher-end models for turbines or compressors requiring advanced diagnostics.
• Environmental Needs: Prioritize this model for installations with temperature fluctuations or moderate vibration (≤5g), as its compact design balances durability and cost.
• System Integration: Ensure your PLC/DCS accepts 4–20 mA inputs；use a protocol converter if digital communication (e.g., Modbus) is required (check optional factory configurations).
• Budget: Ideal for applications where full-spectrum vibration analysis is unnecessary, offering essential monitoring at a competitive price point.

7. Precautions

• Installation:
  • Mount the module at least 10 cm away from power cables to minimize EMI；use shielded cables for sensor connections.
  • Calibrate sensors using a certified vibration shaker to ensure accurate baseline measurements.
• Configuration:
  • Set alarm thresholds according to ISO 1940 (bearing vibration standards) or manufacturer guidelines for your equipment.
  • Test relay outputs during commissioning to confirm alarm triggers at predefined levels.
• Maintenance:
  • Inspect module LEDs monthly to verify power and signal status；clean air vents to prevent dust buildup in high-dust environments.
  • Replace the module every 10 years or after sustained exposure to extreme temperatures, as per Bentley’s recommended lifecycle.
• Safety:
  • De-energize the system before connecting sensors or servicing the module to prevent electrical shocks.
  • In explosive environments, ensure installation complies with local safety standards (e.g., ATEX Zone 2) using approved conduit and enclosures.
