Product Introduction & Supply Chain Strategy
The Bently Nevada 1900/65A-01-01-01-00-00 is a flexible, stand-alone general-purpose equipment monitor designed for continuous machinery protection. This specific configuration includes an AC power supply adapter (110–220 VAC), a local attached display, and a 35 mm DIN rail bracket, accommodating four dynamic transducer channels and four temperature inputs.
Securing this unit as New Surplus protects plant operations from unexpected trip system failure on essential pumps, fans, or motors. Refurbished monitoring electronics often carry degraded ADC components or dried-out internal capacitors, leading to false trips or failed alarm relays during critical vibration events. Stocking a verified New Surplus unit preserves OEM accuracy, reduces Total Cost of Ownership (TCO), and ensures immediate drop-in replacement capability.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Perform Lock-Out/Tag-Out (LOTO) on the incoming 110–220 VAC line and disconnect machine trip interlocks.
- Put on an anti-static wrist strap connected to a verified ground lug.
- Back up the existing monitor configuration file via the 1900 Configuration Software or document all channel setpoints from the attached display.
Stage 2: Removal
- Unplug the removable terminal blocks for sensor inputs, temperature channels, relays, and 4–20 mA outputs.
- Disconnect the main AC power input wiring.
- Release the DIN rail mounting latch on the base of the enclosure and remove the monitor from the 35 mm rail.
Stage 3: Installation (Clone & Seat)
- Snap the new 1900/65A-01-01-01-00-00 module onto the 35 mm DIN rail.
- Upload the saved configuration file (.190) from your PC to the new monitor via the software interface.
- Reinsert all terminal block connectors into their respective ports, verifying ground shield connections.
Stage 4: Power-On & Testing
- Measure incoming AC voltage to confirm supply levels fall within 110–220 VAC limits.
- Apply power and observe the local display; verify that the green OK LED illuminates solid without system fault messages.
- Perform a loop check on 4–20 mA outputs and test relay logic prior to restoring automatic machine trip functions.
Firmware/Software Versions & Upgrade Notes
The Bently Nevada 1900/65A monitor relies on internal non-volatile memory to manage its operating system and user settings.
- Software Compatibility: Requires Bently Nevada 1900 Configuration Software for setup, scale factor adjustments, and filter assignments.
- System Interoperability: Software settings must match sensor sensitivities (e.g., 200 mV/mil proximity probes or 100 mV/g accelerometers) to avoid calculation errors.
- Firmware Mismatch Risk: Importing a configuration file created under a higher software release into an older firmware monitor may trigger invalid parameter errors. Always verify firmware versions via the attached display menu before loading system files.
Frequently Asked Questions (FAQ)
1. Is this Bently Nevada 1900/65A-01-01-01-00-00 unit brand new or refurbished?
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
2. What do the option numbers in “190065A-01-01-01-00-00” signify?
The options translate as follows: 01 = 110–220 VAC External Power Supply; 01 = Attached Display Module; 01 = 35 mm DIN Rail Mounting Bracket; 00 = Standard (No) Agency Approvals; 00 = No Modbus Communications Option.
3. Can I upgrade this unit to support Modbus communications later?
Yes. Although the -00 communication option indicates Modbus is not pre-configured, you can add Modbus functionality using the optional 1900/01 communications upgrade package or external gateway.
4. Does the attached display allow complete configuration of the monitor?
The attached display module allows users to view real-time channel variables, active alarms, and perform minor adjustments. However, full system setup—such as setting up complex relay logic or custom filtering—requires the 1900 Configuration Software connected via PC.
5. What warranty coverage comes with this New Surplus monitor?
Every New Surplus 1900/65A-01-01-01-00-00 unit includes a full 12-month replacement warranty. Units ship in ESD-safe packaging along with individual physical and functional quality inspection reports.
