Features:
- RMU101 identity: ABB names the exact spare as the serial measurement board
- Three-pole interface: the board is paired with battery 3HAC044075-001
- Position-data service: battery work concludes with revolution-counter updating
3HAC044168-001 belongs to the robot measurement chain rather than the controller computer or fieldbus system.
Its three-pole battery arrangement is a hard selection boundary because ABB warns users not to replace or convert the contact.
The board's service value depends on clean ESD-safe handling and a controlled battery-change procedure that protects synchronization data.
Apter Power can review 3HAC044168-001 board markings, connector type, physical condition, battery requirement, and official maintenance evidence.
