1900/65A-01-01-03-01-00 Bently Nevada

1900/65A-01-01-03-01-00 Bently Nevada Control Unit

Product  Description：

• • • The part number 1900/65A-01-01-03-01-00 breaks down into the following specific technical parameters based on the Bently Nevada ordering guide. The Power Supply option 01 indicates an 110/220 VAC 50/60 Hz power input. The I/O Configuration option 01 specifies the inclusion of specific terminal blocks and mounting hardware for standard installations. The Relay Option 03 indicates the configuration of the internal mechanical relays used for alarm and trip functions. The Mounting Option 01 typically refers to a standard bulkhead or panel mount arrangement. Finally, the 00 suffix usually indicates no special agency approvals or standard factory configurations. Key technical specifications include four transducer inputs that support Accelerometers, Velocity Transducers, or Proximitor Sensors, along with four 4 to 20 mA recorder outputs. The unit also features an integrated display for local data visualization and buffered transducer outputs for easy connection to external diagnostic instruments.

      Product Advantages

      One of the primary advantages of the 1900/65A-01-01-03-01-00 is its standalone capability. Unlike many high-end protection systems, it does not require an external rack or separate power supply module, making it ideal for isolated equipment. The monitor offers a high degree of flexibility, allowing users to configure channels for different measurement types such as radial vibration, thrust position, or casing acceleration. It provides robust protection through high-speed hardware logic that can trigger relays within milliseconds of an alarm condition. Additionally, the small form factor allows it to be installed in tight spaces or directly onto machine skids, reducing wiring costs significantly compared to centralized monitoring rooms.

      Important Precautions and Warnings

      When installing or maintaining the 1900/65A-01-01-03-01-00, several precautions must be observed to ensure personnel safety and equipment integrity. First, because this specific model uses AC power (110/220 VAC), all wiring must be performed by qualified personnel with the power disconnected to avoid electrical shock. Proper grounding is essential to minimize electrical noise which can cause false alarms in sensitive vibration measurements. Users must ensure that the environment does not exceed the rated operating temperature of the unit, typically ranging from -20°C to +70°C. Furthermore, when configuring the relay logic, it is critical to verify the "Fail-Safe" vs. "Non-Fail-Safe" settings to ensure the machinery is protected in the event of a monitor power failure. Regular calibration and verification of the transducer loop are recommended to maintain the accuracy of the protection system.

      Product Applications

      The Bently Nevada 1900/65A-01-01-03-01-00 is widely applied across various industries for the protection of "Balance of Plant" or "Essential" machinery. Common applications include the monitoring of small to medium-sized electric motors, centrifugal pumps, and fans used in HVAC or cooling tower systems. It is also frequently found in the power generation sector for monitoring auxiliary equipment like lube oil pumps and air compressors. In the water and wastewater industry, it provides vital protection for large pumps and blowers. Because of its four-channel capacity, it is perfectly suited for a single machine train consisting of a motor and a driven pump, where two channels monitor the motor bearings and two monitor the pump bearings.
