125800-01 is the manufacturer-listed, non-isolated Keyphasor I/O module with internal terminations for the Bently Nevada 3500/25 Enhanced Keyphasor Module. It routes Keyphasor transducer signals into the rear of the rack so the associated front module can process shaft-reference events for the 3500 system.
125800-01 is chosen when internal termination is required and signal isolation is not part of the configuration. The transducer type, signal range, termination method and need for isolation should be checked together because nearby 3500/25 I/O part numbers are not interchangeable descriptions of the same option.
Internal terminationProvides the standard internal-termination rear I/O arrangement for the 3500/25. |
Non-isolated signal pathMaintains the standard, non-isolated Keyphasor input option defined by the manufacturer. |
Two-channel system roleSupports the two-channel Enhanced Keyphasor front module used for shaft-reference processing. |
Official fact: 125800-01 is non-isolated; 125800-02 is the isolated internal-termination option designed for magnetic pickups. Engineering consequence: substituting one for the other can change the intended signal interface. Action: confirm transducer type and isolation requirement from the existing configuration before ordering.

Choose it when the approved design calls for the non-isolated, internal-termination rear I/O option. Confirm the transducer type and signal range before ordering.
Identify it as the rear Keyphasor I/O module and list the Enhanced Keyphasor front module separately when both are needed.
Record terminal positions, polarity, shield treatment, transducer type, channel use, and all parallel signal connections before disconnection.
Confirm the non-isolated input selection, transducer signal, polarity, internal termination, front-and-rear pairing, and channel configuration.
Check the transducer waveform and gap, input polarity, terminal wiring, threshold configuration, and front-module status before replacing the I/O card.
Send both front and rear part numbers, transducer type, expected signal range, channel purpose, internal-termination requirement, quantity, and labels.
Technical identity and product facts were checked against 3500/25 Enhanced Keyphasor Module Datasheet, 141532 Rev. Y. Verify the installed nameplate, revision, companion module and project documentation before commissioning.
