Dedicated 24 V DC digital I/O expansion for SINUMERIK 802S and 802C machine-tool control installations.
Siemens 6FC5511-0CA00-0AA0 is the SINUMERIK 802S/802C digital I/O module specified with 16 digital inputs and 16 digital outputs. The official Siemens NC 60 catalog identifies a 24 V DC input supply, IP20 protection and compact 80 × 125 × 120 mm dimensions. It is intended for exact installed-base expansion or replacement, so controller generation, adapter hardware and field wiring must be confirmed before procurement.

Apply this exact model only after confirming the installed system, electrical design and project documentation.
Add discrete machine inputs and outputs to a compatible SINUMERIK 802S or 802C control installation.
Restore an existing machine using the same complete order number and connector arrangement.
Connect permitted 24 V DC sensors and actuators after validating the original wiring documentation.
| Check point | What to confirm | Procurement note |
|---|---|---|
| Controller platform | Confirm SINUMERIK 802S or 802C hardware generation. | Do not apply specifications from later SINUMERIK families. |
| I/O capacity | Verify the project requires 16 inputs and 16 outputs. | Match signal assignment to the machine documentation. |
| Expansion hardware | Check whether adapter block 6FC5511-0CB00-0AA0 is required. | Inspect mounting and connector condition. |
| Electrical fit | Confirm 24 V DC field circuits and protective measures. | Follow the machine builder wiring plan. |
| Lifecycle evidence | Current official source does not show a PLM designation. | Request traceable documentation for condition and revision. |
The current official Siemens source available for 6FC5511-0CA00-0AA0 confirms the product and its technical data but does not display a lifecycle designation. No Active, Classic, Phase Out or Discontinued status is asserted on this page.
It provides 16 digital inputs and 16 digital outputs.
The Siemens NC 60 catalog identifies it for SINUMERIK 802S and 802C systems.
The official catalog specifies 24 V DC.
Approximately 80 mm wide, 125 mm high and 120 mm deep.
Siemens lists adapter block 6FC5511-0CB00-0AA0 for one-time I/O expansion; verify the installed assembly.
No current Siemens lifecycle wording was found, so the page deliberately leaves the lifecycle unclassified.
