Siemens 6ES7972-4AA50-0XA0 performs automatic changeover between PRB segments in a SIMATIC DP arrangement. It is identified as the PRB segment controller. Its permissible supply is 20.4–28.8 V DC. The housing carries an IP20 protection rating. These specifications apply to the segment controller itself.
The changeover function determines this component’s place in the PRB installation. It must remain distinct from the Power Rail Booster in an equipment list. A request for a booster does not identify the same component. During service, use the installed segment-switching arrangement to identify the required spare. The complete article number keeps the controller’s role clear throughout procurement.
Provide automatic changeover between PRB segments in the corresponding SIMATIC DP installation.
Distinguish the segment controller from the power rail booster when checking the installed components and spare-parts list.
Use the complete article number to match a replacement segment controller to the existing system design.
No. This article identifies the PRB segment controller, an automatic changeover switch between PRB segments.
No. The segment controller and booster are different components, so their electrical data must be checked separately.
Its IP20 rating requires a suitable installation environment and any additional enclosure protection required by the system.
Send the complete label and the surrounding PRB installation so the exact component can be identified.
The quotation covers only the items explicitly listed. Identify any other PRB components required as separate order items.
Provide your destination and preferred courier when ordering. Dispatch is arranged promptly after payment and order preparation.
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.
Most products are covered by a warranty of up to 12 months, subject to the applicable terms and conditions. If any product-related issue occurs during the warranty period, our team will assist you and provide an appropriate solution.
Relevant datasheets and technical literature can be provided with the goods, offering useful information for product identification, installation, operation, and maintenance.
We understand the importance of minimizing equipment downtime. Our team responds promptly to inquiries and provides professional assistance with product information, quotations, order status, shipping, and after-sales questions.
We serve customers worldwide and provide reliable assistance from inquiry to delivery and after-sales service, ensuring clear and timely communication throughout the process.
We continue to source discontinued, obsolete, and hard-to-find automation parts from various brands, helping customers maintain existing equipment and reduce downtime caused by spare parts shortages.
