Siemens 6ES7412-1XJ05-0AB0 is the CPU 412-1 central processing unit for SIMATIC S7-400 automation systems. It provides 288 kbyte of work memory, divided equally between program code and data. The integrated MPI/DP interface supports communication at rates up to 12 Mbit/s. Load memory can be expanded with a suitable memory card. The CPU is powered through the system backplane. Engineering requires the supported STEP 7 package and hardware update.
The 6ES7412-1XJ05-0AB0 executes the control program and coordinates the configured S7-400 station. Program organization includes cyclic operation and supported interrupt handling. The communication interface links the controller with the appropriate automation participants. Memory-card selection and backup arrangements must suit the installed application. A replacement should be checked against the existing hardware configuration and firmware requirements. Preserve and verify the project and retained data before changing the controller.
Process configured logic, arithmetic and data handling within the S7-400 automation station.
Connect compatible MPI or PROFIBUS participants through the integrated MPI/DP interface and the configured network role.
Organize event handling using the supported startup, time, process and diagnostic organization blocks.
This CPU is specified with an MPI/DP interface. Ethernet communication requires a suitable system communication arrangement.
No. Memory cards expand the supported load memory, not the integrated work memory.
Back up the STEP 7 project and review the memory-card and battery-backup arrangements before removing the existing CPU.
The CPU reference, firmware and hardware catalog entry must match the project requirements. Verify these before commissioning.
We check identification and condition and can discuss the required product records before dispatch. The agreed warranty period is 12 months.
Yes, confirmed available stock is arranged for prompt dispatch after payment, with the final courier schedule confirmed for your destination.
With 20+ years of industry experience, we serve customers worldwide and have built long-term relationships across the UK, Russia, UAE, India, Venezuela, and more.
Our experienced team provides reliable pre-sales and after-sales support, helping customers select suitable products and resolve purchasing concerns.
We supply leading automation brands covering PLCs, DCS, I/O modules, drives, motors, power supplies, communication modules, and more.
A wide range of products is available from stock, including discontinued, obsolete, and hard-to-find parts, helping reduce sourcing time.
We value long-term cooperation and treat every customer with honesty, respect, responsibility, and care.
From a single replacement part to complete automation projects, we are ready to support your needs and build a long-term partnership.
Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.
We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.
In Practice: An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.
Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.
In Practice: A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
