TB825 technical selection worksheet
Use the complete TB825 designation when requesting this S800 optical ModuleBus media converter. The installation must be checked against the actual equipment marking, because a shared product family does not establish identical ratings, options or approvals.

This table identifies the published family facts for TB825. Treat any unlisted option as a selection question, not as an implied specification for TB825. Consult the current ABB data and the installed nameplate before release.
Match the ordered configuration
The most important purchase question for TB825 is: Check fiber type, ST termination, optical budget, cluster layout, supply and compatibility with the FCI/modem. Record any missing suffix, revision, calibration or approval with the supplier.
Ask whether the offered TB825 item includes the required terminals, accessories and documentation. Any suggested substitute needs a line-by-line comparison, not an assumption based on the family prefix.
Installation boundary
Before fitting TB825, isolate the process or electrical system under the site procedure and check the drawing, connection, mounting and environmental limits.
Document the original terminals and settings for TB825. Reapply only approved wiring and parameter changes; retain the previous unit identification for traceability.
What the device does
The work assigned to TB825 is specific: Extend an approved S800 ModuleBus optical connection across the plant. Record the controlled process, feeder or network point in which TB825 operates.
Check the upstream source and the downstream load or signal as a complete path. For TB825, an apparently matching connector or housing does not establish functional equivalence.
Commissioning evidence
The practical acceptance check for TB825 is: Verify both optical ends, cluster discovery and fault indications after controlled reconnection. Capture actual readings, states or faults rather than reporting only that the device powered up.
Close the work order for TB825 with the observed test result, final configuration and responsible reviewer. If a safety or protective function is involved, follow the site-specific validation procedure.
