Bently Nevada 1900-65A-01-01-02-00-00 General Purpose Equipment Monitor
A general-purpose machinery monitor configured with external AC power, attached display, bulkhead mounting and no optional communications selection.
Product Profile
1900-65A-01-01-02-00-00 identifies a configured Bently Nevada 1900/65A General Purpose Equipment Monitor. The platform combines four configurable transducer inputs, four temperature inputs, six relay outputs and four 4–20 mA recorder outputs in one machinery-monitoring unit.
In this order code, the 01 selections identify the documented external AC power arrangement and attached display, while 02 selects bulkhead mounting. The remaining 00 selections retain the base approval and communication choices. The complete 1900-65A-01-01-02-00-00 string must be used because neighboring codes alter supplied hardware.

System Role
Monitors vibration, position and temperature on general-purpose rotating equipment.
Drives six configurable relay outputs for alerts, danger states or machine logic.
Provides four recorder outputs for control-system or historian integration.
Stores configuration without volatile-memory dependence and supports Ethernet setup.
Compatibility
- Match sensor type, wiring, scale factor, full-scale range and bias behavior for every dynamic input.
- Confirm thermocouple type or RTD wiring for each temperature channel.
- Verify the attached-display and bulkhead-mounting mechanics before preparing the panel.
- Use the installed nameplate to confirm AC input details; do not wire from the shortened family description.
- The 00 communications selection does not create the optional Modbus path; any external integration must follow the supplied configuration.
Applications
- General-purpose vibration and temperature monitoring on pumps, fans, compressors and motors.
- Compact machinery-protection panels needing local display, relays and recorder signals.
- Replacement of the exact configured monitor without changing sensors or panel mounting.
FAQ
What backup is required before replacing 1900-65A-01-01-02-00-00?
Export the complete channel, alarm, relay, recorder and display configuration and record all sensor and terminal assignments.
Can 1900-65A-01-01-02-00-00 be ordered from the base 1900/65A name alone?
No. The complete suffix controls power, display, mounting, approval and communication choices.
Why might a sensor read differently after fitting 1900-65A-01-01-02-00-00?
Incorrect transducer type, scale factor, full-scale range, wiring or gap and bias settings can shift the value even when the monitor is healthy.
How should the six relays on 1900-65A-01-01-02-00-00 be recommissioned?
Prove each logic expression, delay, latching mode, energized state and external circuit under an approved machine-safe test plan.
What should be checked before connecting power to 1900-65A-01-01-02-00-00?
Read the installed input nameplate, verify the external power-supply execution, protective device, earth connection and panel wiring against the order code.
