Product introduction

The 1900/65A-01-01-01-00-00 from Bently Nevada is a compact yet powerful machinery protection system controller, designed to monitor and protect critical rotating equipment in industrial environments. As a key component in Bently Nevada’s mid-range monitoring portfolio, this controller combines advanced measurement capabilities with intuitive operation, providing real-time machinery health data while delivering critical protection functions to prevent catastrophic failures.

Engineered for versatility, the 1900/65A-01-01-01-00-00 accepts inputs from a variety of sensors including proximity probes, velocity sensors, and accelerometers—seamlessly integrating with termination panels like the 146031-01 to consolidate monitoring points. Its 7-inch touchscreen interface provides instant access to vibration trends, alarm status, and diagnostic information, while flexible communication options enable integration with plant-wide control systems. Whether deployed in power generation, petrochemical, or manufacturing facilities, this controller forms the cornerstone of effective machinery health management programs.

Core advantages and technical highlights

Integrated protection and monitoring: The 1900/65A-01-01-01-00-00 combines continuous machinery protection with comprehensive condition monitoring in a single 3U rack-mount unit. Unlike basic protection systems, it provides both real-time alarm capabilities to prevent equipment damage and historical trending for predictive maintenance, eliminating the need for separate monitoring devices. This integration reduces system complexity and improves data correlation between protection events and long-term machinery degradation.

Flexible channel configuration: With 4 fully configurable channels, the controller adapts to diverse monitoring requirements, accepting inputs from proximity probes (for shaft position and vibration), velocity sensors, accelerometers, and temperature sensors. Each channel features advanced signal processing with configurable filters, scaling, and alarm thresholds, enabling precise customization for specific machinery types and failure modes.

Intuitive operation interface: The 7-inch color touchscreen provides user-friendly access to critical information through customizable dashboards, real-time waveforms, and historical trend graphs. Operators can quickly navigate between machinery assets, acknowledge alarms, and access diagnostic tools without specialized training. The interface supports multiple languages and configurable user permissions to ensure secure operation.

Enhanced connectivity: Equipped with Ethernet, RS485, and USB ports, the 1900/65A-01-01-01-00-00 offers flexible integration options with DCS, SCADA, and asset management systems via Modbus protocols. This connectivity enables centralized data collection, remote monitoring, and integration with predictive maintenance software platforms. The controller also supports firmware updates and configuration backups via USB for simplified maintenance.

Safety integrity: Certified to IEC 61508 and ISO 13849-1 (SIL 2), the controller provides reliable protection functions with built-in diagnostic coverage exceeding 90%. Its redundant power supply options and fault-tolerant design ensure protection functions remain operational during component failures, making it suitable for safety-critical applications.

Typical application scenarios

In combined cycle power plants, the 1900/65A-01-01-01-00-00 monitors gas turbine auxiliaries including lube oil pumps, cooling fans, and generator exciters. Connected to 146031-01 termination panels, it consolidates vibration data from multiple 330130-040-01-00 proximity probes and temperature sensors, providing both real-time protection against catastrophic failures and historical data for performance trending. The controller’s Ethernet connection integrates with the plant’s DCS, enabling operators to monitor machinery health alongside process variables.

Within chemical processing facilities, the controller protects critical centrifugal pumps and agitators in hazardous areas. Its ATEX Zone 2 certification ensures safe operation near potentially explosive atmospheres, while the SIL 2 rating provides reliable protection against machinery failures that could cause process upsets. The touchscreen interface allows local operators to monitor pump vibration and bearing temperatures, while Modbus RTU connectivity transmits data to the plant’s asset management system for predictive maintenance planning.

In manufacturing plants, the 1900/65A-01-01-01-00-00 serves as the central monitoring hub for production line motors, gearboxes, and compressors. It accepts inputs from accelerometers and velocity sensors installed on key machinery, providing immediate alarm notifications for abnormal vibration levels while storing long-term trend data. Maintenance teams use the historical trending capabilities to schedule repairs during planned downtime, maximizing production availability while preventing unexpected equipment failures.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the 1900/65A-01-01-01-00-00, ensure the 19-inch rack is properly grounded and has adequate ventilation. Verify the power supply matches the controller’s requirements (100-240V AC or 24V DC) and is protected by appropriate circuit breakers. Plan cable routing for sensor connections (via termination panels) and communication links, ensuring separation between power and signal cables to minimize interference.

Mounting procedure: Secure the controller in the 19-inch rack using the provided mounting ears, ensuring proper alignment and secure attachment. Connect the power supply, observing correct polarity for DC installations. Establish connections to termination panels using shielded twisted-pair cables, ensuring proper grounding of cable shields at both ends. Connect communication cables (Ethernet, RS485) to the appropriate ports, and secure all connections with cable ties to prevent accidental disconnection.

Commissioning steps: Power on the controller and perform initial configuration using the touchscreen interface or configuration software. Define input channels, specifying sensor types, measurement ranges, and scaling factors. Configure alarm thresholds for each measurement parameter, setting appropriate warning and trip levels based on machinery specifications and industry standards. Test relay outputs to verify proper connection to shutdown systems and alarm annunciators. Perform communication testing to ensure data transmission to upstream systems.

Maintenance suggestions: Inspect the 1900/65A-01-01-01-00-00 monthly for loose connections, dust accumulation, or signs of overheating. Clean ventilation filters quarterly using compressed air to maintain cooling efficiency. Verify alarm functionality annually by simulating sensor inputs and confirming proper relay operation. Backup configuration settings regularly to USB storage. Check for firmware updates periodically and apply updates during scheduled maintenance outages. Calibrate the controller’s internal reference standards every 2 years using certified calibration equipment.
