What this SIPLUS CPU is and what it handles
The Siemens SIPLUS 6AG1455-2AD00-4AA0 is a ruggedised CPU module designed for motion control applications in harsh environments. It operates on 24 V nominal (20.4... 28.8 V), draws up to 46 W, and packs 388 MB of work memory with 512 kB retentive memory for unlimited buffer duration. The module supports 6 servo axes, 6 vector drives, and 6 DRIVE-CLiQ interfaces, making it a natural fit for multi-axis coordinated motion on machine tools or packaging lines. Rated Class 3C4 with salt spray per EN 60068‑2‑52 severity 3; operates 0…55 °C, stores -40…+70 °C, tolerates 100 % humidity; IP20 / UL open type.
Connectivity and I/O handling
This CPU brings one PROFINET interface, two PROFIBUS ports, two USB ports, and two Industrial Ethernet ports. It can handle 24 digital inputs at 1 µs resolution with reproducibility of 10 µs. Signal thresholds: '0' from -3 to +5 V, '1' from 15 to 30 V. Maximum lamp load is 11 Hz, inductive load 2 Hz. The supplied plug covers must stay on unused interfaces during operation to maintain the IP20 rating and protect the coatings. Electrical isolation is not present on this module, so shared reference potential is assumed. Plan for common-mode voltage limits on the fieldbus segments accordingly.
Sourcing and lifecycle
For compliance documentation, the module carries cULus approval for USA and Canada, and RCM for Australia. No ROHS or REACH statements are listed in the provided spec, but these are typically included in the SIPLUS declaration pack. Request them with your RFQ if required for your quality department.
