Description

Brief Product Description

The ALSTOM ESVI1 L54E1100BB is a high-precision analog and logic I/O card specifically engineered for the rigorous demands of railway signaling and train control systems. It features 16-bit resolution and opto-isolated channels to provide accurate, interference-free data acquisition in harsh electromagnetic environments.

Precision Signal Acquisition for Rail Infrastructure

The ALSTOM ESVI1 L54E1100BB serves as a fundamental interface for modern railway signaling and automated train control architectures. This card processes critical environmental and mechanical data through 8 high-accuracy analog inputs. By utilizing a 16-bit Analog-to-Digital Converter (ADC), the module achieves a remarkable ±0.1% full-scale accuracy, which is essential for safety-critical monitoring. Engineers integrate this card into systems requiring precise voltage (±10V DC) and current (±20mA) measurements to ensure that train speeds, positioning, and track status remain within strict operational parameters. Consequently, this precision directly supports the overall safety and efficiency of global rail networks.

Advanced Electrical Isolation and Environmental Resilience

Because railway environments present significant electrical noise and extreme temperature fluctuations, ALSTOM designed the ESVI1 L54E1100BB with robust protection features. The board incorporates 4 opto-isolated channels that physically decouple sensitive logic circuits from external field wiring, effectively neutralizing common-mode noise and voltage surges. Furthermore, the hardware maintains stable performance across an expansive temperature range from -25°C to +70°C. The non-condensing 95% humidity tolerance ensures that the card remains operational in damp tunnels and diverse climates. These protective measures minimize maintenance requirements and prevent signal degradation over the lifecycle of the rail signaling equipment.

Compact Integration and Global Standards Compliance

The ESVI1 L54E1100BB emphasizes space efficiency without compromising industrial-grade durability. Its compact dimensions allow for high-density mounting within standard rail control cabinets, where enclosure space often commands a premium. Manufactured in the USA, this module adheres to stringent international safety standards required for mission-critical transportation infrastructure. The durable construction supports long-term storage in extreme conditions, while the lightweight 0.38kg design simplifies field replacement and hardware upgrades. This I/O card represents an optimized solution for operators seeking to balance high-performance data conversion with the rugged physical requirements of heavy rail applications.
