8237-1594 超速检测装置 利用三重模块化冗余架构

【产品详情】

8237-1594 利用三重模块化冗余架构和 2/3 投票逻辑来准确确定不安全情况和单点故障。

型号8237-1594来自伍德沃德Protech-GII系列。它是一种超速检测装置，可以配备任何尺寸的涡轮机。它与燃气轮机、水轮机和蒸汽轮机配合使用，在过度加速时安全有效地关闭它们。8237-1594 型还具有 MPU 检测和耐硫涂层。它可用于 3C2 级环境，对 S02 和 H2S 气体具有长期耐受性。三重模块设计允许在一个模块出现故障时进行在线维修。A、B 或 C 模块可以在系统其余部分仍在线和运行时更换。该产品还可以执行常规速度测试，并记录这些测试的结果。这是通过内部生成器完成的，并确保一切顺利运行。

该型号的速度读数为 4 至 20 mA，它使用 2 个投票架构中的 3 个和 8237 个独立继电器。它是使用高压和低压电源输入的隔板安装。它还配备了Modbus通信。

【英文介绍】

The 8237-1594 utilizes a triple modular redundant architecture and 2/3 voting logic to accurately determine unsafe situations and single points of failure.

Model 8237-1594 is from the Woodward Protech-GII series. It is an overspeed detection device that can be equipped with turbines of any size. It works with gas, water and steam turbines to shut them down safely and efficiently in case of excessive acceleration. Model 8237-1594 also has MPU detection and a sulfur-resistant coating. It can be used in 3C2 level environments with long-term tolerance to S02 and H2S gases. The triple module design allows for online repair in the event of a module failure. A, B, or C modules can be replaced while the rest of the system is still online and running. The product can also perform routine speed tests and record the results of these tests. This is done through internal generators and ensures that everything runs smoothly.

This model has a speed reading of 4 to 20 mA, and it uses 3 of 2 voting architectures and 8,237 individual relays. It is mounted using high - and low-voltage power input partitions. It is also equipped with Modbus communication.
