Bently 3500/32 125720-01

Description

• Technical Specifications
  • Power Parameters: Typical power consumption reaches 6 watts, which is fully compatible with the power distribution system of the 3500 series rack and imposes minimal load on the overall system power supply.
  • Relay Configuration: Adopts a structure where two single-pole double-throw relays are connected into a double-pole double-throw configuration, with 4 independent relay output channels. Each relay supports a contact life of 100,000 cycles when operating at 5A, 24Vdc or 120Vac.
  • Arc Suppression Performance: Standard-equipped with 250Vrms arc suppressors that effectively reduce arc generation during relay switching to protect relay contacts and extend service life.
  • Physical Dimensions: Measures 241mm in height, 24.4mm in width and 99.1mm in depth, with a net weight of 0.4kg, conforming to the unified installation dimensions of 3500 series modules.
  • Environmental Ratings: Operates within a temperature range of -30°C to +65°C and can be stored at -40°C to +85°C. It maintains stable performance in an environment with 95% non-condensing humidity. The epoxy-sealed housing enhances its resistance to dust and corrosion.
  • Switching Mode: Each channel can be switch-selected between normally energized and normally de-energized states to adapt to different external equipment control requirements.
• Function Features
  • Programmable Alarm Logic: Each relay is equipped with alarm drive logic that can be programmed with AND and OR logic. It can accept alarm inputs including warnings and dangers from any monitor channel combination in the rack, enabling customized alarm response strategies.
  • Independent Channel Configuration: All 4 relay output channels can be programmed independently to execute custom voting logic. This flexibility allows the module to meet diverse control needs in different industrial scenarios without mutual interference between channels.
  • Intuitive Status Indication: Equipped with three types of front-panel LED indicators. The OK LED lights up when the module operates normally. The TX/RX LED flashes to indicate smooth communication with other modules in the rack. The CH ALARM LED illuminates when a relay channel enters an alarm state, facilitating rapid status identification and troubleshooting.
  • Scalable Installation: Multiple 4-channel relay modules can be installed in the 3500 rack according to actual system requirements. This scalable design enables the system to expand control capabilities as the number of monitored equipment increases.
  • Built-in Diagnostic Capabilities: The module continuously monitors its own relay status and communication links. When abnormalities such as relay contact failure or communication interruption occur, it can promptly feed back fault information through status indicators and system software to support proactive maintenance.
• Application Scenarios
  • Power Industry: Deployed in thermal, hydro and nuclear power plants to connect with monitoring modules of steam turbines, generators and coal mills. When abnormal vibration or speed exceeds thresholds, it drives relays to trigger alarms or cut off relevant power supply circuits to prevent major equipment failures.
  • Oil and Gas Industry: Installed on offshore drilling rigs, pipeline compressors and gas turbines. It responds to equipment fault signals such as bearing wear and rotor imbalance, activates emergency shutdown procedures or adjusts valve opening through relay actions to ensure the safety of oil and gas extraction and transportation processes.
  • Aerospace Field: Used in the protection and control systems of aircraft engines and transmission systems. It converts real-time monitoring data of key components into relay control signals, enabling rapid response to abnormal conditions and ensuring the stability and safety of aerospace equipment during operation.
  • Metallurgical and Steel Industry: Applied to rolling mills, blast furnace fans and air compressors in steel plants. In high-temperature and dusty environments, it relies on its rugged design to receive equipment vibration and temperature alarm signals, driving relays to control auxiliary equipment startup and shutdown and avoiding production interruptions caused by equipment failures.
  • General Industrial Automation: Suitable for papermaking, cement and railway industries. It controls pumps, conveyors and other equipment in production lines. Through linkage with monitoring systems, it realizes automated alarm and interlocking protection, improving the reliability and efficiency of the entire production process.
