Siemens 6FC5111-0CA04-0AA0 SINUMERIK 840 DMP Compact 1AI Analog Input Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Siemens 6FC5111-0CA04-0AA0 is a SINUMERIK 840 DMP Compact 1AI analog input module for distributed I/O in legacy CNC automation systems. It provides one analog input channel for integrating an analog signal into compatible SINUMERIK control architectures. The module is associated with SINUMERIK 840C, 840CE, 840D and 840DE CNC control systems.
When preparing a replacement, match the exact Siemens part number, the SINUMERIK control platform and the DMP Compact distributed I/O architecture. The module supports rated input voltage options of ±10 V and ±500 mV, so the required signal range must match the existing machine installation before the spare is commissioned. This part is intended as a direct maintenance replacement for established CNC equipment rather than as a generic analog input module.
The 6FC5111-0CA04-0AA0 is a discontinued Siemens component used to maintain existing SINUMERIK 840-based machine tools. For a failed analog input module, check the part number, control-system platform, DMP Compact architecture and required input range before fitting a replacement. A correctly matched spare can support repair and continued operation of legacy CNC automation equipment.

Replacement and Spare Part Considerations
Use the complete Siemens part number 6FC5111-0CA04-0AA0 when identifying a spare. Compatibility checks should include the SINUMERIK 840C, 840CE, 840D or 840DE control platform and the SINUMERIK DMP Compact distributed I/O architecture.
The required analog signal range is a key replacement check because this module is associated with rated input voltage options of ±10 V and ±500 mV. Confirm that the selected module and the existing machine installation use the required range before commissioning the replacement.
