Product Precautions
- Bently Nevada 1900/65A-00-01-01-00-00 supports local observation of machine condition in a DIN-mounted installation, bringing vibration and temperature variables onto an attached display while relay logic handles the configured protective actions.
Measurement inputs: Four transducer channels plus four temperature channels
Local access: Attached display; PC configuration through Ethernet
Protective outputs: Six programmable relays and four 4-20 mA recorders
Local access: Attached display; PC configuration through Ethernet
Protective outputs: Six programmable relays and four 4-20 mA recorders
Four transducer channels process acceleration, velocity, radial vibration, thrust, position or speed according to the selected sensor and software settings. Four temperature inputs accept E, J, K or T thermocouples or two- and three-wire RTDs. The attached display presents channel information; full configuration is transferred using the PC Ethernet connection and retained in non-volatile memory.
Six SPDT relays can combine OK, Alert and Danger status through programmable expressions with up to 50 operands per relay. Latching and energized-state selections are independent. AND ignores bypassed channels while True AND includes them, which makes the exact voting expression significant during channel maintenance. Four independently assigned 4-20 mA outputs update every 100 ms and support up to 600 ohms loop resistance under the applicable loop-supply conditions.
The monitor operates from 18-36 V DC and mounts on a 35 mm DIN rail. Typical monitor demand is 0.35 A and 8.5 W, with maximum values of 1 A and 14 W. DIN mounting alone does not provide a weatherproof enclosure. The final 00 selection omits Modbus. Ethernet remains available for configuration transfer, while the four recorder outputs provide independently assigned analog variables to receiving equipment.

Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
System and supply context: 18-36 V DC, attached display without a separate display cable, 35 mm DIN rail mounting, no agency-approval option and no Modbus option. Sensors and external receiver circuits are selected to match the configured input and output channels.
Application scope: Suitable general-purpose machines may combine vibration, temperature and discrete protection. The examples describe integration roles, not preconfigured alarm settings or a universal machine-protection design.

Local condition display
Read configured channel values at the machine-monitoring position using the attached display.Combined thermal and vibration monitoring
Pair compatible bearing-temperature circuits with the selected vibration measurements.Programmable protection contacts
Use reviewed relay expressions to combine warning, danger and channel-health states.Analog trend recording
Send selected variables to recording or control inputs using four independently assigned current loops.
Prepare Bently Nevada 1900/65A-00-01-01-00-00 for its configured installation using these checks.
Verify power and mounting
Check DC polarity, supply capacity and DIN attachment before energizing the monitor.
Identify each sensor
Record transducer type, sensitivity, wiring and temperature-sensor selection.
Protect trip circuits
Use the site-approved maintenance state before altering relays or alarm settings.
Check output assignments
Match each recorder variable and full scale to the receiving input.
Prove voting logic
Test normal, alarm, Not OK, bypass and reset behavior against the approved logic.
Separate configuration and process data
Use Ethernet for configuration; this order code does not include Modbus process communication.

FAQ View All FAQ
-
How is local channel information viewed on 1900/65A-00-01-01-00-00?The BB01 selection includes an attached display, without a separate display cable. It presents channel readings and allows minor setting changes; full configuration remains a PC software task.
-
What DC capacity should be allocated to 1900/65A-00-01-01-00-00?The monitor accepts 18-36 V DC. Typical demand is 0.35 A and 8.5 W; maximum values are 1 A and 14 W. Include the rest of the cabinet load when sizing the supply.
-
Does the DIN mount on 1900/65A-00-01-01-00-00 provide environmental sealing?No. A 35 mm DIN attachment supports the monitor mechanically; it is not the weatherproof-housing selection. Provide the enclosure protection required by the installation.
-
Can the temperature channels of 1900/65A-00-01-01-00-00 use different sensor technologies?The four inputs can be configured for E, J, K or T thermocouples or two- and three-wire RTDs. Each channel must use the correct sensor selection and wiring.
-
What remains stored when 1900/65A-00-01-01-00-00 loses its DC supply?The configuration is held in non-volatile memory. Retain a controlled PC copy as well, so channel processing, setpoints, relay logic and recorder assignments can be checked after service.
-
How quickly do recorder signals update on 1900/65A-00-01-01-00-00?The four 4-20 mA recorder outputs update every 100 ms. Each represents its assigned variable and configured full scale, which must match the receiving instrument.
-
How does a maintenance bypass affect AND voting in 1900/65A-00-01-01-00-00?AND ignores bypassed channels; True AND includes them. Prove the intended relay behavior using the actual expression and approved bypass test.
-
Can the attached display replace Modbus for remote data collection on 1900/65A-00-01-01-00-00?No. Local display access does not provide a Modbus Gateway. This final-00 configuration uses relay contacts or assigned recorder loops for external process interfaces; Ethernet still supports PC configuration.
