Features:
- Monitor pairing: Serves a 3500/40M Proximitor monitor position.
- Termination choice: Uses internal terminations in the installed rack.
- Hardware distinction: The internal-termination module differs from external-termination and barrier-equipped versions.
The module sits behind the corresponding 3500/40M monitor position.
Termination style defines the wiring relationship that must be preserved.
Matching the removed I/O module and rear-rack wiring is more reliable than choosing by monitor family alone.

Important Notice: The monitor, transducers, barriers and rack wiring are not included unless stated in the quotation.
- Monitor interface: This I/O board carries the 3500/40M Proximitor channel connections behind the monitor.
- Termination path: Internal terminations keep the field-wiring interface within the specified rack arrangement.
- Wiring continuity: A board exchange should preserve channel-to-terminal assignments for the installed transducers.
- Supply scope: The I/O board does not include the monitor or field transducers unless quoted separately.
- Internal termination: 125680-01 is the documented non-barrier I/O option for this arrangement.
- External termination: Baker Hughes lists 126615-01 as a different 3500/40M I/O module.
- Barrier configuration: 135489-04 has internal barriers and should not be inferred from the 125680-01 outline.
- Selection basis: The removed assembly marking and rack wiring identify the appropriate termination variant.
- Slot identity: The I/O position should correspond to the associated 3500/40M monitor.
- Connector condition: Contact and terminal inspection can prevent a wiring fault during replacement.
- Channel response: Startup checks should confirm monitor recognition and plausible transducer readings.
- Variant mismatch: If the installed rack uses external terminations or barriers, engineering review is needed before fitting this part.
- 3500/40M Proximitor channel termination.
- Internal-termination rack maintenance.
- Condition-monitoring system repair during planned outages.
- Exact-part spares for installed 3500 racks.
