Product Precautions
- Bently Nevada 1900/65A-01-01-03-00-00 combines local measurement visibility with a windowed protective enclosure, allowing condition-monitoring values to be reviewed without relying on a networked operator station.
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 selected AC option uses an external 110-220 V AC, 50-60 Hz supply. A fiberglass NEMA 4X/IP66 housing with a window door accommodates local observation; cable entries and closure must preserve the enclosure installation. 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: 110-220 V AC, 50-60 Hz through an external supply, attached display without a separate display cable, fiberglass NEMA 4X/IP66 weatherproof housing with a window door, 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-01-01-03-00-00 for its configured installation using these checks.
Verify power and mounting
Check the external AC supply and maintain window-door housing closure and cable-entry sealing.
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.

Technical notes
Power boundary: 110-220 V AC, 50-60 Hz through an external supply. Monitor-side DC demand is not the AC mains input-current rating.
Display selection: The attached display is included without a separate display cable. Remote-display accessories are not implied.
Communication selection: 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.
FAQ View All FAQ
-
Can 1900/65A-01-01-03-00-00 be connected directly to an arbitrary AC terminal?The selected AC option is 110-220 V AC at 50-60 Hz through an external power supply. Use that supply and its approved wiring; do not apply mains voltage to monitor-side DC terminals.
-
What does the window-door enclosure add to 1900/65A-01-01-03-00-00?The CC03 option specifies a fiberglass NEMA 4X/IP66 weatherproof housing with a window door. The completed installation must preserve closure, seals and suitable cable entries.
-
Which controls are available at the attached display of 1900/65A-01-01-03-00-00?The display provides channel information and minor setting access. Use PC configuration software for the complete channel, relay and recorder setup; an attached display is not a full substitute for that workflow.
-
Must a recorder on 1900/65A-01-01-03-00-00 follow the input with the same channel number?No. Each of the four recorders can be assigned a selected channel variable. Trace the assignment and full-scale mapping before interpreting the receiver value.
-
How much loop resistance can 1900/65A-01-01-03-00-00 support on its recorder circuits?The specified maximum is 600 ohms under the applicable 18-36 V DC recorder-loop supply conditions. Include receiver and cable resistance in the loop assessment.
-
Why can a relay remain latched after a measurement returns to normal on 1900/65A-01-01-03-00-00?A relay configured for latching requires a reset after its initiating condition clears. Verify the logic state and reset path; a reset cannot correct an active sensor fault.
-
Are the six contacts of 1900/65A-01-01-03-00-00 all driven by one common alarm rule?No. Each SPDT relay has its own programmable expression, with up to 50 operands. Its energized-state and latching choices must also match the intended circuit.
-
Can 1900/65A-01-01-03-00-00 send event records to a DCS over Modbus?This final-00 build omits the Modbus option. Its configuration Ethernet connection and attached display do not establish Modbus event reporting.
