SIEMENS 6RY1803-0AA25-0AA1 – Digital Output Module | SINAMICS / SIMOREG DC Master Platform
Engineering Background
The SIEMENS 6RY1803-0AA25-0AA1 (alternate part number A5F00133630) is a factory-original digital output module engineered for integration within the SIMOREG DC Master and SINAMICS drive control architecture. Designed to extend the discrete I/O capacity of Siemens DC drive systems, this module delivers deterministic, high-reliability switching outputs essential for industrial process control, motor management, and safety interlock circuits in demanding manufacturing environments.
Product Positioning
Targeted at procurement engineers and maintenance teams operating Siemens SIMOREG 6RA70 / 6RA80 series DC converters and SINAMICS platforms, this module is the OEM-specified replacement and expansion component for digital output signal routing. It is widely deployed in steel mills, paper machines, crane drives, extruder lines, and heavy-duty conveyor systems where precise digital control output is non-negotiable.

Engineering Advantages
- OEM-Specified Component: Direct factory replacement — no firmware re-parameterization required in most SIMOREG/SINAMICS configurations.
- Deterministic Output Switching: Ensures precise timing for interlock, contactor, and safety relay circuits critical in high-inertia drive applications.
- Plug-and-Play Integration: Board-level form factor designed for direct installation into existing SIMOREG drive racks without mechanical modification.
- Extended I/O Expansion: Increases the number of discrete digital outputs available to the drive controller, enabling complex multi-axis or multi-zone process logic.
- Industrial-Grade Reliability: Manufactured to Siemens’ stringent quality standards for continuous-duty industrial environments with high EMI and vibration exposure.
System Architecture & Signal Flow
The 6RY1803-0AA25-0AA1 interfaces directly with the SIMOREG DC Master’s internal CUD (Control Unit DC) or equivalent SINAMICS control board via the drive’s internal bus connector. Digital output signals are generated by the drive’s closed-loop control software (e.g., STARTER, SIMOVIS, or DriveMonitor parameterization) and routed through this module to external actuators, contactors, or PLC digital input cards. The module supports standard 24 V DC logic levels compatible with Siemens SIMATIC S7 PLC I/O modules and third-party DCS systems.

Technical FAQ
Q: Is 6RY1803-0AA25-0AA1 compatible with SIMOREG 6RA70 and 6RA80 series?
A: Yes. This digital output module is designed for the SIMOREG DC Master family including 6RA70 and 6RA80 series converters. Always verify the specific drive firmware version and CUD board revision with your Siemens documentation before installation.
Q: What is the difference between order number 6RY1803-0AA25-0AA1 and board number A5F00133630?
A: The 6RY1803-0AA25-0AA1 is the Siemens commercial order number (MLFB) used for procurement. A5F00133630 is the internal PCB/assembly board number stamped on the module itself. Both refer to the identical component.
Q: Can this module be used as a standalone digital output card outside of a SIMOREG drive?
A: No. This module is designed exclusively for internal installation within the SIMOREG DC Master or compatible SINAMICS drive enclosure and requires the drive’s internal power supply and bus interface to operate.
Q: Do you provide a certificate of conformity or test report?
A: Yes. A pre-shipment inspection report is available upon request. CE declaration of conformity documentation from Siemens can be provided for new OEM units.
Q: What is the lead time for this part?
A: In-stock units ship within 3–5 business days. For sourced units, typical lead time is 7–15 business days depending on origin. Contact us for real-time stock status.
