KUKA 00-127-755 ESC 3.0 extended safety board

KUKA 00-127-755 extended safety board for KRCED05 controllers, with board-level interfaces and condition left explicit as unknown.

Controller safety-board role

Rebuilt from individual evidence

Evidence and limits

Radwell identifies 00-127-755 as a KUKA PC board and extended safety board, ESC 3.0 Extended, for KRCED05 controllers. Fanucworld labels the same exact reference as a safety PCB.

The evidence places the board inside the KRCED05 controller as an extended safety-board element. The exact safety signals, outputs, wiring, firmware dependencies, revision, repair history and unit condition remain unknown.

Unknown: the exact safety signals, wiring, firmware dependencies and controller interfaces; the exact safety outputs, interlocks and runtime behavior; and the condition, revision, repair history and current availability of an individual unit.

Inferences

Inferred system position: the board is installed inside the KRCED05 controller as an extended safety-board element.
Confidence: medium
Rationale: The exact-reference listing names the hardware as an extended safety board and explicitly ties it to KRCED05 controllers.
- www.radwell.com — retrieved 2026-09-11; medium confidence
Inferred function: the board controls an extended safety-board function within a KRCED05 controller.
Confidence: medium
Rationale: The sources identify the exact board as a safety PCB or extended safety board for the named controller family, but do not document individual safety signals.

Unknowns

Unknown: the exact safety signals, wiring, firmware dependencies and controller interfaces for this board.
Confidence: low
Missing evidence: No KRCED05 wiring or board-level interface documentation was captured for this exact reference.
Unknown: the exact safety outputs, interlocks and runtime behavior are not documented in the captured sources.
Confidence: low
Missing evidence: The captured exact-reference listings do not expose board schematics or runtime safety behavior.
Unknown: the condition, revision, repair history and current availability of an individual unit.
Confidence: low
Missing evidence: Seller service and inventory statements do not establish the condition of a particular unit.
