Main Features and Advantages

The ELMA 1900002919-0000R subrack is defined by its exceptional modularity and ruggedness. Its most significant feature is the flexible backplane system, which can be configured to support various data bus architectures like VME, CompactPCI, or custom passive backplanes, allowing system integrators to tailor the platform to exact application requirements. This future-proofs the investment, as the chassis can be repurposed for different projects by simply changing the internal cards. The all-aluminum construction provides a lightweight yet incredibly rigid structure that effectively dissipates heat and provides excellent shielding against electromagnetic interference, ensuring the stable operation of sensitive electronic components in electrically noisy industrial settings.

The integrated, managed cooling system is a critical advantage. The chassis is designed for optimal front-to-rear airflow, with fans that are often hot-swappable, allowing for maintenance without powering down the entire system—a crucial feature for high-availability applications. The front panel typically features status indicators for power and system health, while the robust construction includes features to dampen shock and vibration, protecting mounted components from failure. The design of the 1900002919-0000R prioritizes serviceability, with easy access to all components, tool-less module insertion and extraction in many configurations, and standardized mounting, drastically reducing mean time to repair (MTTR) and overall lifecycle costs.

Application Field

The ELMA 1900002919-0000R finds its primary application in any industry that requires ruggedized, reliable computing and electronic control in a packaged form factor. In industrial automation, it is used as the core enclosure for building custom PLCs, motor control centers, and embedded controllers on the factory floor. Within the transportation sector, it houses control and monitoring systems for railway applications, where resistance to shock and vibration is mandatory. The energy sector, including power generation and distribution, utilizes these subracks for protection relays and grid management systems that must operate uninterruptedly for years.

Its EMI shielding and cooling capabilities make it suitable for telecommunications infrastructure, housing networking and signal processing equipment. In defense and aerospace, the rugged nature of the 1900002919-0000R makes it an ideal choice for ground vehicle computing, radar systems, and test & measurement equipment that must perform reliably in extreme environmental conditions. Essentially, this subrack is the go-to solution for system designers who need a proven, off-the-shelf mechanical platform for mission-critical electronic systems outside of a benign data center environment.
