The Siemens 6ES7400-2JA10-0AA0 offers a rugged aluminum rack solution for the SIMATIC S7-400 platform. This UR2-H model serves both central and distributed system architectures with equal effectiveness. Its 18-slot design splits into two distinct segments, each providing 9 slots for module installation. Moreover, the rack features physically separated communication and P buses, a critical attribute for redundancy-focused applications.
The UR2-H rack provides 18 slots in total, dividing them into two independent groups of nine slots each. This segmentation enables users to build logically isolated subsystems within a single physical chassis. For instance, one segment can house the primary CPU and I/O, while the other accommodates a redundant backup set. Additionally, the separated communication bus and P bus prevent signal interference between data pathways, ensuring stable system operation.
Siemens constructs this rack from high-grade aluminum, which delivers excellent strength-to-weight performance. The material choice also aids in passive heat dissipation, contributing to overall system thermal management. Its robust build withstands the mechanical stresses commonly encountered in industrial control cabinets.
The 6ES7400-2JA10-0AA0 carries a comprehensive set of international certifications. These include CE, UKCA, UL, FM, RCM, KC, EAC, and CCC markings. Therefore, system integrators can deploy this rack in projects across North America, Europe, Asia, and other regions without additional compliance hurdles.
The rack measures 482.5 mm in width, 290 mm in height, and 27.5 mm in depth. These dimensions conform to standard 19-inch cabinet specifications, simplifying integration into existing infrastructure. It weighs approximately 3 kg, making it relatively lightweight for its size and capacity.
This rack supports an operating temperature range from 0 °C to 60 °C. During storage or transportation, it tolerates temperatures between 0 °C and 70 °C. Consequently, it maintains structural integrity and performance across a wide variety of environmental conditions.
Installing the SIMATIC S7-400 UR2-H rack requires only basic mechanical skills. First, secure the rack horizontally within a standard 19-inch cabinet using the provided mounting hardware. Next, verify that the cabinet provides adequate ventilation around the rack's ventilation paths. Finally, install the power supply, CPU, and I/O modules into the appropriate slots according to your system architecture plan.
When populating the two segments, consider distributing critical components evenly to maximize redundancy benefits. For high-availability systems, place redundant CPUs in separate segments to isolate potential faults. Furthermore, utilize the separated bus structure to assign communication-heavy modules to one bus while keeping time-critical I/O on the other.
