Product Overview

The Alstom ESVI1 current and voltage signal input/output board is a high-performance signal conversion and conditioning module designed by Alstom specifically for industrial automation control systems, rail transit traction systems, and power equipment monitoring systems. The core responsibility of this product is to achieve precise acquisition, isolation and conditioning, standardized conversion, and stable output of current and voltage signals in industrial sites, and to build a reliable signal transmission bridge between sensors/actuators and core control units. Integrating high-precision signal isolation, anti-interference conditioning, and multi-channel signal processing functions, it has core advantages such as precise signal transmission, reliable isolation protection, and strong environmental adaptability. It can provide stable current and voltage signal interaction guarantee for the system in complex industrial working conditions. It is a key signal switching component in Alstom series automation equipment and large-scale industrial control systems.

As the core carrier of industrial grade current and voltage signal interaction, the ESVI1 signal input/output board strictly follows international industrial electrical standards and Alstom's strict quality control specifications. It is suitable for harsh operating environments such as high and low temperatures and strong electromagnetic interference, and is widely used in fields such as power plants, rail transit, and industrial manufacturing that require high accuracy and reliability in current and voltage signal transmission. It provides core signal support for precise monitoring and stable control of the system.

Core functions

1. Accurate acquisition of multi-channel current and voltage signals

Integrated multi-channel independent current and voltage acquisition interfaces can accurately collect various current signals (such as 4~20mA, 0~1A, 0~5A) and voltage signals (such as 0~10V, ± 10V, 0~220V AC) in industrial sites. Equipped with high-precision sampling circuit, it has high sampling accuracy and fast response speed, and can capture the dynamic changes of current and voltage signals in real time, providing real and accurate raw signal data for the core control unit, ensuring the accuracy of system monitoring and control.

2. Signal isolation conditioning and anti-interference protection

Built in high-performance optoelectronic or magnetic isolation modules achieve full isolation design between input, output, and power supply. The isolation voltage is high, which can effectively block common mode interference, differential mode interference, and signal distortion caused by potential difference in industrial sites. Equipped with professional signal filtering circuits, it can further suppress interference signals such as electromagnetic radiation and voltage surges, ensuring the stability and integrity of signal transmission.

3. Standardized signal conversion and flexible output

The collected non-standard current and voltage signals can be accurately converted into standardized signals compatible with the core control unit (such as 4-20mA current signals, 0-10V voltage signals), supporting flexible configuration of signal range. Equipped with multiple types of output interfaces, it can achieve stable output of current or voltage signals according to downstream device requirements, adapt to the signal reception needs of different control modules, and improve system compatibility.

4. Full link signal monitoring and fault alarm

Equipped with full link signal monitoring function, it can detect input signal exceeding range, signal loss, signal distortion, and abnormal operation of the board itself (such as overheating, overvoltage, circuit faults, etc.) in real time. When an abnormality occurs, it can quickly trigger a fault alarm signal and feedback it to the main control unit, while executing corresponding signal locking or protection actions to avoid the fault signal affecting the normal operation of the system and ensure the safety of equipment and the system.

5. Industrial grade stable design and convenient adaptation

Adopting industrial grade reinforced design, it has a wide temperature working range and high protection level, and can operate stably for a long time in harsh industrial environments. Support standardized installation methods and convenient terminal connections, adapt to different specifications of wires, facilitate on-site installation, debugging, and later maintenance; At the same time, reserved configuration interfaces can be used to flexibly adjust signal acquisition range, output type and other parameters according to on-site working conditions, improving scene adaptability.
