Siemens 2XV9450-1AR23 E10433-E9600-H110 Central Clock Module – SICLOCK TM Plant

Technical Dossier

Product Details And Specifications

The Siemens SICLOCK TM Plant Central Clock (Part No. 2XV9450-1AR23, Firmware/HW Variant E10433-E9600-H110) is a precision time synchronization master unit designed for industrial plant networks operating on 90–230V AC/DC. As Siemens has progressively phased out legacy SICLOCK hardware in favor of SINEC and SCALANCE-based NTP/PTP solutions, sourcing this specific variant has become a genuine procurement challenge — particularly for facilities running long-lifecycle DCS, SCADA, or PLC architectures that cannot be upgraded on short notice.

Procurement Specifications

Note: Because this part is discontinued, inventory authenticity and traceability documentation are non-negotiable. DriveKNMS provides full chain-of-custody records upon request.

Procurement decisions on legacy industrial components are rarely just about unit price. The true cost of ownership for a time synchronization module like the 2XV9450-1AR23 must account for three dimensions:

We are not a catalog distributor. DriveKNMS operates as an active sourcing agent for industrial automation components, with a specific focus on Siemens, ABB, Schneider Electric, and Rockwell Automation legacy parts.
