125800-02 is the official isolated Keyphasor I/O module with internal terminations for the Bently Nevada 3500/25. The manufacturer designed this option for magnetic pickups and for configurations where the Keyphasor signal must be isolated from other parallel-connected devices.
125800-02 connects at the rear of the rack and works with the separate 3500/25 front module. Its isolation changes the input interface and introduces more phase shift than the non-isolated version, so the choice should follow the real transducer and measurement purpose rather than only the connector layout.
Isolated input pathProvides signal isolation for configurations that connect the Keyphasor signal to multiple devices. |
Magnetic-pickup focusManufacturer-designated internal-termination option for magnetic-pickup inputs. |
Rear-rack configurationPairs with the two-channel 3500/25 front module while keeping terminations inside the rack. |
Official fact: the isolated input is intended primarily for magnetic pickups; a Proximitor sensor requires an external power supply with this option. Engineering consequence: an unverified substitution can leave the transducer unpowered or change phase performance. Action: confirm the transducer, supply method and use of the signal before installation.

Use it when the approved design requires the isolated internal-termination input, especially for the documented magnetic-pickup or shared-signal arrangement.
The isolated option does not supply that sensor directly, so confirm the required external power source and its wiring before connection.
Review the allowed input type, expected speed and signal level, and the isolated path phase behavior against the measurement requirement.
Record the pickup or probe type, external supply, terminal positions, threshold settings, channel configuration, and parallel connections.
Check pickup speed and signal amplitude, polarity, external supply where required, terminal wiring, threshold configuration, and front-module status.
Provide the front module number, pickup or probe type, expected speed and signal range, isolation purpose, external power arrangement, 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.
