The Bently Nevada 125704-01 is a rack I/O module used in the 3500/34 triple-modular-redundant relay arrangement. The TMR design groups three relay channels for hardware voting so that a configured relay function is not dependent on a single relay path. This listing is for part number 125704-01 only; the mating front module, field wiring and configured logic are separate project items.

Compatibility and ordering checks

Confirm part number 125704-01 from the installed module label.
Verify that the project uses a 3500/34 TMR relay assembly, not a standard 3500/32 relay module.

Check the mating front module, rack slot and field wiring condition before replacement.

Procurement notes

Supply the front-module number and a clear photo of the existing rear I/O label when requesting a replacement. The exact 125704-01 suffix matters because standard relay and TMR relay hardware are not interchangeable by description alone.
