Bently 3500/33 149992-01

Description

• Technical Specifications
  • Relay Configuration: 16 independent single-pole double-throw (SPDT) relays, each with a contact rating of 30V DC/2A and 120V AC/1A. Relay contact life exceeds 100,000 operations at full load, with arc suppression diodes (250Vrms) standard for all channels to extend service life.
  • Power Parameters: Operates on 24V DC power supply (tolerance ±10%), with a maximum power consumption of 8 watts. Draws a nominal current of 333mA at 24V DC, compatible with the 3500 series rack’s power distribution system.
  • Response Performance: Relay actuation time ≤ 10ms, release time ≤ 5ms, ensuring rapid response to critical fault signals from the monitoring system.
  • Physical & Installation: Dimensions of 241.3 mm (depth) × 24.4 mm (width) × 120.7 mm (height), net weight of 1.2 kg. Designed for rack mounting in 3500 series standard racks, with backplane connectivity eliminating external wiring between the module and other 3500 components.
  • Environmental Ratings: Operating temperature range: -30°C to +65°C; storage temperature: -40°C to +85°C. Operates in 0–95% non-condensing humidity, with a conformal-coated circuit board for dust and moisture resistance. Complies with IEC 60068-2 for shock and vibration resistance.
  • Communication & Compatibility: Communicates with 3500 rack interface modules via the backplane, supporting Modbus TCP/IP, Ethernet/IP, and Profinet protocols. Fully compatible with 3500 System Configuration Software and System 1 condition monitoring software for remote configuration and status monitoring.
• Function Features
  • High-Density 16-Channel Design: Consolidates 16 independent relay channels into a single full-height module, reducing rack space requirements and simplifying wiring for multi-point monitoring systems. Each channel operates independently to avoid cross-interference.
  • Programmable Logic & Voting Schemes: Supports custom logic programming (AND/OR/NOT) for alarm triggering, allowing users to link relay actions to single or multiple monitor channels. Supports 1-out-of-1, 2-out-of-2, or 2-out-of-3 voting schemes for redundant monitoring scenarios.
  • Hot-Swap & Redundant Operation: Enables on-site module replacement without shutting down the 3500 rack, minimizing maintenance downtime. Supports dual-module hot-standby redundancy, ensuring continuous relay output even if one module fails.
  • Intuitive Status Monitoring: Front-panel LED indicators for each channel (Active/Alarm) and module health (Power OK, Communication OK) provide real-time visibility of operation. Fault codes are transmitted to the 3500 rack for remote diagnostics via software.
  • Non-Volatile Configuration Storage: Saves all programming logic, channel settings, and relay configurations in non-volatile memory, retaining data during power outages or module replacement. Configuration files can be backed up to a PC for easy system replication.
  • Arc Suppression & Contact Protection: Built-in arc suppression diodes for each relay prevent electrical arcing during switching, protecting relay contacts from wear and extending operational lifespan in high-cycle applications.
• Application Scenarios
  • Power Generation Industry: Deployed in thermal, hydro, and nuclear power plants to control steam turbines, generators, and coal mill protection systems. Triggers emergency shutdowns, fuel cutoff, or auxiliary pump activation when vibration, temperature, or speed anomalies are detected, preventing major power outages.
  • Oil & Gas Industry: Installed on offshore drilling rigs, pipeline compressors, and gas processing plants. Controls valve positioning, emergency depressurization systems, and pump interlocks in response to bearing wear, rotor imbalance, or pressure fluctuations, ensuring safety in hazardous environments.
  • Petrochemical Industry: Used in refineries and chemical plants to monitor reaction towers, agitators, and gearboxes. Links with 3500 vibration and temperature modules to activate fire suppression systems, isolate faulty equipment, or adjust process parameters, mitigating risks of leaks or explosions.
  • Metallurgical Industry: Applied to steel mill rolling mills, blast furnace fans, and air compressors. Operates reliably in high-temperature, dusty conditions to trigger lubrication system activation, roll gap adjustments, or production line shutdowns, avoiding costly equipment damage.
  • Heavy Machinery Manufacturing: Integrated into test benches for large industrial pumps, motors, and turbines. Controls test chamber safety interlocks, data logging triggers, and emergency stop circuits during product validation, ensuring accurate performance testing and operator safety.
  • Water & Wastewater Industry: Deployed in water treatment plants to monitor pumps, blowers, and mixers. Triggers standby equipment activation, overflow prevention systems, or maintenance alarms when vibration or bearing temperature exceeds thresholds, ensuring uninterrupted water supply.
