4. Functional Features

• Universal Multi-Channel Monitoring: Supports up to 8 input channels, each configurable for vibration, axial displacement, or rotational speed—eliminating the need for multiple specialized monitors. This flexibility makes it suitable for diverse machinery (e.g., monitoring 4 vibration points on a turbine and 4 displacement points on a compressor).
• High-Visibility Real-Time Display: The 4.3-inch color TFT LCD provides clear visualization of parameter values (numeric and graphical), channel status (green = normal, yellow = alarm, red = trip), and fault codes. The backlit design ensures visibility in low-light control rooms, and multi-language support caters to global operations.
• Programmable Alarm & Trip Logic: Each channel includes a dedicated Form C relay, allowing users to set custom threshold levels for “warning” (alarm) and “critical” (trip) conditions. Relays support latching (requires manual reset) or non-latching (auto-reset when parameters normalize) modes, ensuring alignment with machinery-specific safety protocols (e.g., turbine trip at 250 μm vibration, pump alarm at 100 μm).
• Data Retransmission & Integration: The 8 analog retransmission outputs mirror scaled input signals, enabling seamless integration with DCS/SCADA systems for centralized plant monitoring. The RS-485/Ethernet ports (Modbus protocols) support remote configuration, real-time data streaming, and historical data logging—critical for predictive maintenance (e.g., trend analysis of vibration data to schedule bearing replacements).
• Comprehensive Diagnostics: Integrates self-diagnostic functions to monitor internal components (power supply, display, communication ports) and external connections (signal conditioner inputs). Faults—such as open input wires, shorted outputs, or power loss—trigger on-screen fault codes and LED alerts, and are transmitted via the communication port to control systems. This reduces troubleshooting time and minimizes downtime.
• Rugged Environmental Performance: Operates reliably in temperatures from -40°C to +70°C, humidity from 5% to 95% RH (non-condensing), and under shock/vibration conditions. Its robust construction and corrosion-resistant materials ensure performance in harsh industrial settings, including offshore platforms, steel mills, and desert power plants.
• User-Friendly Operation: The membrane keypad enables intuitive navigation of menus, adjustment of parameters, and acknowledgment of alarms. Basic configuration (e.g., setting measurement ranges, alarm thresholds) can be completed on-site without external software, while advanced configuration (e.g., saving profiles, bulk adjustments) is supported via the communication port and Bently’s proprietary software.

5. Application Scenarios

• Power Generation Industry:
  • Deployed in coal-fired, natural gas, and nuclear power plants to monitor steam turbines, gas turbines, and generators. It aggregates data from 8 signal conditioner channels—tracking radial vibration (4 channels) and axial displacement (4 channels) across multiple shafts. The module’s trip relays trigger emergency shutdowns if vibration exceeds 250 μm (turbine critical limit), while analog outputs feed real-time data to the plant’s DCS. The high-visibility display allows operators to quickly assess machinery health, ensuring continuous power generation.
• Oil & Gas Industry:
  • Used in offshore drilling platforms, onshore refineries, and pipeline compressor stations. It monitors centrifugal compressors, reciprocating pumps, and gearboxes by consolidating 8 channels of vibration and speed data. ATEX/IECEx certification ensures safe operation in Zone 2 hazardous areas (e.g., refinery process units with flammable gases). The RS-485 port enables integration with SCADA systems, allowing remote monitoring of pipeline compressors and quick response to alarms (e.g., pump vibration exceeding 150 μm).
• Petrochemical Industry:
  • Integrated into ethylene crackers, polymer reactors, and process pumps. It tracks vibration (6 channels) and axial displacement (2 channels) from probes on reactor agitators and pump shafts. The module’s color display provides operators with clear visibility of parameter trends, while alarm relays alert teams to abnormal conditions (e.g., agitator vibration rising to 120 μm, indicating impeller wear). The rugged design withstands high temperatures in reactor rooms (up to 70°C) and humidity in outdoor pump stations.
• Metallurgical Industry:
  • Applied in steel mills and aluminum smelters to monitor rolling mill drives, fan motors, and hydraulic pumps. It aggregates 8 channels of vibration data from rolling mill drives—critical for detecting gearbox wear or bearing failure that could disrupt steel production. The module’s diagnostics quickly identify issues like open probe wires, reducing maintenance time and minimizing unplanned downtime in high-volume manufacturing.
• Marine & Shipping Industry:
  • Installed on cargo ships, tankers, and offshore support vessels to monitor marine diesel engines, propeller shafts, and auxiliary pumps. It tracks vibration (4 channels) and speed (4 channels) from engine and pump probes. The rugged design withstands shock/vibration from rough seas, while the backlit display ensures visibility in dim engine rooms. Trip relays shut down engines if vibration exceeds 300 μm, preventing catastrophic failure during long voyages.
• Heavy Manufacturing & Mining:
  • Used in cement plants, mining crushers, and conveyor systems. It consolidates 8 channels of vibration data from crusher shafts (4 channels) and conveyor motor bearings (4 channels). The module’s analog outputs feed data to the mine’s SCADA system, enabling remote monitoring of crushers in remote mining sites. Alarm relays alert maintenance teams to bearing wear (e.g., conveyor motor vibration exceeding 100 μm), allowing scheduled replacements and reducing downtime.
