Product Overview
The Bently Nevada 1900/65A 167669-02 functions as a versatile, standalone machinery protection system designed for general-purpose equipment. Unlike rack-based systems, this compact "Universal Device Monitor" provides continuous monitoring and protection for essential assets like pumps, motors, fans, and small compressors. We supply this unit as 100% Brand New and Original, offering a high-integrity safety solution for machinery that does not require the extensive channel density of a 3500 rack.

Engineering Advantages
-
Hybrid Monitoring Capabilities: The 167669-02 simultaneously processes dynamic vibration signals and static temperature data. It accepts 2-wire or 3-wire accelerometers, velocity sensors, and proximity probes alongside RTDs and thermocouples, providing a holistic view of machine health in a single device.
-
Standalone Safety Logic: This module operates independently of a central PLC or DCS to provide hardware-level protection. The six onboard relays trigger alarms or machine trips instantly based on user-defined setpoints, ensuring asset safety even if network communications fail.
-
Seamless Control System Integration: Four 4-20 mA outputs and Modbus® compatibility allow the 1900/65A to stream real-time data directly to your plant’s control interface. This facilitates easy trending and predictive maintenance scheduling without specialized software.
-
Optimized for Decentralized Installations: The small footprint and rugged design make the 167669-02 ideal for mounting in small enclosures local to the machine. This reduces long-distance sensor cabling runs, effectively lowering installation costs and minimizing signal noise.
FAQs
1. Is the 167669-02 compatible with existing Bently Nevada proximity probes?
Yes. The 1900/65A supports standard 3-wire proximity transducer systems (such as the 3300 XL series). It provides the necessary -24Vdc power to the Proximitor® sensor and processes the resulting voltage signal.
2. Can I configure this monitor without a 3500 Rack Configuration Software?
The 1900/65A uses its own dedicated 1900 Configuration Software. You connect via a serial or Ethernet port to define transducer types, scale factors, and relay alarm logic.
3. What is the difference between the 167669-01 and the 167669-02?
The 167669-02 designates a specific hardware configuration, often relating to power supply options or specific agency approvals (like ATEX or North American hazardous area ratings). Always match the full part number to your specific site safety requirements.
4. Does this unit support speed measurements?
Yes. One of the four transducer inputs can be configured to accept a pulse signal from a proximity probe or magnetic pickup for shaft speed (RPM) monitoring and overspeed protection logic.
