特征

该板是 Mark VIe 控制系统的重要组成部分，该系统以其在高要求环境中的强大控制能力而闻名，例如涉及 GE 航改涡轮机的环境。

该选件板与 PPRA 涡轮机 I/O 包配合使用，提供关键的紧急跳闸功能，使系统能够快速监测和应对异常涡轮机状况。该主板设计用于三重模块化冗余 （TMR） 配置，提高可靠性并确保在关键条件下可靠运行。

关键输入和输出

客户输入端子：输入可通过两种类型的连接器访问，即 24 点可插拔栅栏端子（H1A 或 S1A）。48 点可插拔欧式盒式端子（H3A 或 S3A）。这些端子便于安装和快速连接到各种客户输入。

无源脉搏率设备：六个扇形无源脉率设备通过感应涡轮轴上的齿轮产生的脉冲来监控涡轮机速度。这些设备最多支持三个轴，每个轴有两个传感器，提供准确的测量，并馈送到紧急跳闸逻辑中。

固态输出触点：该板包括 24 V 直流 TMR 投票固态输出触点，用于在紧急情况下触发跳闸动作。输出包括 TREAH1A、H3A 与 WREAH1A 和 TREAS1A、S3A 与 WREA 等组合。这些配置提供了一种高度可靠、故障安全的方法来激活涡轮机关闭。

电压检测电路：该板具有四个电压检测电路，可在 24-125 V dc 范围内监控跳闸串电压。此功能确保电路板能够准确检测可能表明不安全操作条件的电压变化。

触点输入：电路板的WREAS1A部分有四个 24 V 直流触点输入，为基于硬件或特定状态的跳闸信号提供额外的选项。输入通过 WREA 板上的 JH1 连接器供电，确保可靠地检测可能需要紧急停机的任何问题。

速度中继器输出：该板为六个速度输入中的每一个提供一个速度中继器输出。这些输出可以利用 RS-232 或 RS-422 发射器，复制每个受监控轴的脉搏率信号，使外部系统能够准确跟踪涡轮机速度。

trait

The board is an essential part of the Mark VIe control system, which is known for its strong control capabilities in demanding environments, such as those involving GE Aero turbines.

This option board is used in conjunction with the PPRA turbine I/O package to provide critical emergency trip functionality, enabling the system to quickly monitor and respond to abnormal turbine conditions. The motherboard is designed for triple modular redundancy (TMR) configuration to improve reliability and ensure reliable operation in critical conditions.

Key inputs and outputs

Customer input terminals: Inputs can be accessed through two types of connectors, namely 24-point pluggable fence terminals (H1A or S1A). 48-point pluggable European box terminal (H3A or S3A). These terminals are easy to install and quickly connect to a variety of customer inputs.

Passive pulse rate devices: Six fan-shaped passive pulse rate devices monitor turbine speed by sensing pulses generated by gears on the turbine shaft. These devices support up to three axes, each with two sensors, providing accurate measurements and feeding into emergency trip logic.

Solid State output contacts: The board includes 24 V DC TMR voting solid state output contacts for triggering trip action in case of emergency. Outputs include TREAH1A, H3A with WREAH1A and TREAS1A, S3A with WREA and other combinations. These configurations provide a highly reliable, fail-safe method to activate turbine shutdowns.

Voltage Detection circuit: The board has four voltage detection circuits to monitor the trip string voltage in the range of 24-125 V dc. This feature ensures that the board can accurately detect voltage changes that could indicate unsafe operating conditions.

Contact input: The WREAS1A section of the board has four 24 V DC contact inputs that provide additional options for hardwares or state-specific trip signals. The input is powered via a JH1 connector on the WREA board, ensuring reliable detection of any issues that may require an emergency shutdown.

Speed repeater output: The board provides a speed repeater output for each of the six speed inputs. These outputs can take advantage of RS-232 or RS-422 transmitters that replicate the pulse rate signal of each monitored shaft, allowing external systems to accurately track turbine speeds.
