Model Overview
Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 is a general-purpose equipment monitor with four transducer inputs and four temperature inputs. The two exact order strings are retained together because their option fields identify different monitor configurations within the same family.
For Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00, each transducer input can be configured for supported accelerometer, piezo-velocity or proximity-sensor signals, while channels 5–8 process thermocouples or 2- and 3-wire RTDs. Processed variables feed relay, recorder and buffered outputs.
The front-panel display, configuration software and Modbus interface provide access to the monitor values and settings for Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00. The exact suffix remains the selection record for the installed option set.

Operating Characteristics
Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 processes multiple variable types in one compact monitor, with each channel assigned its own measurement and alarm behavior.
Speed and frequency
Up to four speed measurements can be calculated from proximity inputs, with the documented 100–100,000 rpm range and selected frequency pass band.
Temperature channels
Channels 5–8 accept Type E, J, K and T thermocouples or 2/3-wire RTDs, with values shown in °C or °F.
04
Monitoring and Control
Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 turns processed variables into local indication, relay action, recorder outputs and communications data.
Alarm contacts
The six relay outputs change state from the configured OK, Alert and Danger conditions of the selected variables.
Recorder path
Four 4–20 mA recorder outputs and a dedicated buffered output expose selected values for downstream control or recording.
Configuration access
The front panel, configuration software and Modbus path provide access to channel setup, status and monitor values for Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00.

Common Questions
Why does Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 show an unexpected engineering value?
For Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00, compare the channel sensor family, units, full-scale setting and filter with the installed transducer. A proximity input, accelerometer and temperature input cannot share one assumed scaling.
How can Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 feed a PLC without using an alarm contact as an analog value?
Use the four 4–20 mA recorder outputs or the dedicated buffered output from Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 for the selected measurement. Relay contacts represent configured states; they do not replace the analog measurement path.
What should be checked when a temperature channel on Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 is unstable?
Confirm whether the channel on Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 is configured for the installed Type E, J, K or T thermocouple, or for a 2- or 3-wire RTD. The wrong sensor type or wire arrangement changes the displayed temperature and alarm behavior.
How can a customer verify a speed alarm from Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00?
Check the selected proximity pulse source, speed-channel assignment and 100–100,000 rpm range in Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00, then compare the front-panel value with the recorder or Modbus value. This separates pulse wiring from scaling errors.
Why might a Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 relay change while the displayed value looks normal?
For Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00, compare Alert and Danger thresholds, delay settings, OK status and relay mapping. A relay can be responding to a configured state or channel fault rather than to the value currently being watched.
How can the two Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 option records be kept from being mixed?
Keep both complete Bently Nevada 1900/65A-00-00-01-00-00 / 1900/65A-00-01-01-00-00 strings on the quotation and wiring record. Their option fields identify the exact installed monitor configuration, so a shortened 1900/65A label is not enough for commissioning.
