BENTLY 3500/93 135785-02

• Power Requirements: Powered directly by the BENTLY 3500 rack backplane; operates on 5 VDC (supplied by 3500/15 Power Supply Module)
• Operating Temperature: -40 °C to +70 °C (-40 °F to +158 °F)
• Humidity: 5% to 95% RH (non-condensing; no dew formation)
• Physical Dimensions: 160 mm (height) x 100 mm (width) x 220 mm (depth); fits standard 3500 19-inch rack slots
• Certifications: UL 508 (Industrial Control Equipment), CSA C22.2 No. 14-19, and ATEX Zone 2 (for hazardous industrial environments)

Functional Features

• Dual-Protocol Data Transmission: Supports both Modbus (industry-standard) and OPC DA protocols, enabling compatibility with nearly all industrial control systems (e.g., Siemens S7, Allen-Bradley ControlLogix) and asset management tools.
• Real-Time Alarm Forwarding: Automatically transmits machinery alarm signals (e.g., “high vibration,” “shaft position deviation”) from 3500 monitors to external systems within <100 ms, ensuring timely operator response.
• Remote Configuration & Diagnostics: Allows users to configure 3500 rack modules (e.g., set alarm thresholds, calibrate sensors) and run diagnostic tests (e.g., backplane communication checks) via Ethernet, eliminating the need for on-site access.
• Data Logging & Storage: Collects and stores historical machinery health data (e.g., vibration amplitude, temperature) locally; supports data export to CSV or Excel formats for trend analysis.
• Redundant Communication Paths: Optional support for dual Ethernet ports (via 3500/93 Redundancy Kit) to ensure communication continuity if one network path fails, critical for mission-critical applications.
• Error Detection & Self-Monitoring: Includes built-in self-diagnostic tools that detect communication errors (e.g., Ethernet cable disconnections, Modbus timeouts) and backplane power issues; sends “module fault” alerts to external systems for proactive maintenance.

Application Scenarios

• Turbomachinery Monitoring: Used in gas turbines, steam turbines, and centrifugal compressors (e.g., in oil refineries or power plants) to transmit vibration, shaft position, and temperature data to DCS for real-time protection.
• Rotating Equipment in Petrochemicals: Integrates with 3500 systems monitoring pumps, fans, and gearboxes in petrochemical plants; forwards health data to SCADA systems to prevent unplanned downtime.
• Power Generation (Coal/Gas-Fired Plants): Connects 3500 vibration and speed monitors on generators and boiler feed pumps to plant DCS, ensuring compliance with safety standards (e.g., NEMA SM23).
• Marine & Offshore Applications: Deployed in offshore oil platforms and LNG carriers to monitor marine diesel engines and propeller shafts; operates reliably in harsh, salt-laden environments (ATEX Zone 2 certified).
• Heavy Industry (Mining/Cement): Transmits data from 3500 systems monitoring crushers, mills, and conveyor drives to mine SCADA systems, optimizing maintenance schedules and reducing equipment failure rates.
• Aerospace & Defense: Used in ground-based gas turbine test cells to send performance data (e.g., rotor speed, exhaust temperature) to test control systems, supporting engine development and qualification.
