1720045 1900/65A Bently Nevada General Purpose Equipment Monitor

Product Overview

The Bently Nevada 1720045 (Series 1900/65A) is a compact, standalone machinery protection system for non-critical “balance of plant” assets such as pumps, motors, blowers, and small compressors.

Offering continuous, automated monitoring in a cost-effective, rack-free design, it provides both primary protection (via relay outputs) and condition monitoring (via 4–20 mA and Modbus outputs), making it ideal for facilities that require high-reliability vibration and temperature monitoring without the complexity of full-scale 3500 series racks.

Detailed Technical Specifications

Key Features and Benefits

• Standalone Intelligence: Operates independently with its own processing logic, eliminating the need for a central rack or controller.

• Redundant Power: Dual power terminals allow connection to two independent DC sources, ensuring continuous operation if one supply fails.

• Real-time Diagnostics: “Monitor OK” relay and front-panel LEDs provide instant identification of transducer faults or internal errors.

• Flexible Configuration: Scale factors, alarm setpoints, and time delays are easily programmed via Bently Nevada configuration software.

• Buffered Outputs: Provides raw signals at the terminal block for connection to portable data collectors (e.g., SCOUT series) for advanced spectrum analysis.

Technical FAQ

Q1: Can the 1720045 monitor both vibration and temperature at the same time?
A: Yes. The module supports simultaneous monitoring of 4 dynamic vibration points and 4 static temperature points, giving a comprehensive view of machine health.

Q2: Does this unit support hazardous area installations?
A: The 1720045 is typically rated for general-purpose, non-hazardous locations. For Zone 2 / Div 2 areas, verify the unit’s certification label or use with external Zener barriers or galvanic isolators.
