Features:
- Supplies internal operating power to the documented UI bus converter assembly.
- Forms the power section of the 6DS4400-8AB TELEPERM hardware.
- Is identified by Siemens as a legacy spare part for converter maintenance.
The current item is the dedicated power-supply board for the UI bus converter rather than a general-purpose cabinet supply. Its connections and location are defined by the parent assembly.
Conditioned power is distributed to the converter electronics so the complete unit can perform its system interface role. The module itself does not provide process I/O channels.
Confirm supply wiring, board position, connector orientation and hardware revision before exchange. Stored energy and external power sources must be isolated in accordance with the cabinet service procedure.
Legacy availability is reviewed by Apter Power against the complete parent converter configuration.
