Bently Nevada 1900/65A-00-00-01-00-00 Equipment Monitor
A 24 VDC DIN-rail 1900/65A monitor without display, approval or communications options.
Product Overview
1900/65A-00-00-01-00-00 is a Bently Nevada general-purpose equipment monitor configured for 18–36 VDC power and DIN-rail mounting. The order code selects no display, no agency approvals and no Modbus communications.
The monitor continuously processes vibration and temperature inputs and can use relay and recorder outputs for general machine monitoring and protection. Configuration software is supplied for channel and logic setup.
Performance
- Accepts four configurable transducer inputs for compatible accelerometers, velocity sensors or proximity sensors.
- Accepts four temperature inputs for supported thermocouple and RTD types.
- Provides six relay outputs, four 4–20 mA recorder outputs and dedicated buffered transducer signals.
- Configuration software sets variables, filters, setpoints, relay voting and bypass modes.

FAQ
Does 1900/65A-00-00-01-00-00 include a local display?
No. The display field is 00; commissioning and status review depend on the monitor indicators and configuration connection.
Can 1900/65A-00-00-01-00-00 connect directly to Modbus?
No. Its final communications option is 00, so a project requiring Modbus needs the correct communication arrangement.
What configuration must be backed up before replacing 1900/65A-00-00-01-00-00?
Save channel types, variables, filters, alarms, relay voting, recorder mappings, bypass settings and tag names.
Can any vibration sensor be connected to 1900/65A-00-00-01-00-00?
Only supported sensor types with the correct wiring, excitation, polarity and configured channel mode should be used.
What information is needed for a 1900/65A-00-00-01-00-00 quotation?
Provide the full order code, channel configuration, sensor list, relay logic, supply, mounting and the required configuration-software version.
What acceptance testing follows a 1900/65A-00-00-01-00-00 replacement?
Inject or simulate each input, verify variables and setpoints, then prove recorder signals, relay voting, bypass behavior and machine trip paths.
