WOODWARD 5233-2089 调速控制器

产品描述

5233-2089是一种断电跳闸超速保护装置。该型号是 Woodward ProTech 203 系列的一部分，该系列在三个相同的速度感应单元中使用 MPU 来监控超速状况。型号 5233-2089 是 220 Vac 版本。该系统中的每个单元都有自己的电源，可产生 +5 V 和 +24 V，与输入电压隔离。

实际机组速度显示在前面板上，共有三个；每个速度传感单元一个。正是通过这些面板对每个单元进行编程，这只能通过钥匙锁访问来完成，以防止未经授权的编程或测试。这也是可以使用电位计调整超速测试频率的地方。所有三个单元都在同一个锁定的、经过 NEMA 4X 认证的外壳中。

5233-2089系统具有多种特性和可用功能，包括：

• 远程复位
• 内置自检
• 功能状态 LED 指示灯（每个速度感应单元都有自己的指示灯）
• 报警输出
• 用于在 PROGRAM 和 MONITOR 模式之间切换的键锁
• 热更换模块化设计

LED 指示灯将显示 MPU 或其接线是否出现故障、相应的速度感应单元是否已跳闸（在这种情况下还会有警报输出），或者该单元的 CPU 是否工作不正常。

5233-2089 超速保护装置的跳闸速度设定点范围为 250 rpm 至 25,000 rpm，故障 MPU 设定点范围为 100 rpm 至 25,000 rpm，故障 MPU 超时范围为 1 秒至 533 分 20 秒。

5233-2089 技术规格

产品描述
Woodward ProTech 203 超速保护系统提供一系列数字超速跳闸装置。这些设备使用三个相同的速度感应单元，配置为三分之二的硬件投票。8200-211 型是一种断电跳闸版本，输入电压为 220 Vac。

5233-2089 系统具有多项针对整体设备故障和系统停机的保护措施。

• 内置频率发生器允许原动机保持在线，同时一次测试一个速度传感单元
• 在单个单元跳闸的情况下，其他两个单元维持正常运行
• 可以在不中断操作的情况下更换单个单元
• 三分之二的投票基于三个单独的速度计算
• 每个速度感应单元都有自己的一组功能状态 LED 指示灯

该 ProTech 5233-2089 系统的速度感应频率范围为 100 Hz 至 32 kHz，触发点频率范围为 250 Hz 至 25 kHz。它的准确度等级为
±(0.05% x 跳变点 (Hz) +2 Hz)。

所有三个速度感应单元都在同一个钥匙锁外壳中，防止未经授权访问编程和测试功能。每个单元都有自己的前面板，配有触摸板和两行 LCD 显示屏，可用于查看单个单元的实际当前速度。

如果满足超速条件并且单元跳闸，则单独的 LED 和警报输出将警告该条件。发生这种情况时，如果当前速度高于先前记录的峰值速度，系统的峰值速度将被更新并存储在非易失性存储器中。即使在一个单元跳闸之后，这种情况也会继续。

Product Description
5233-2089 is a digital overspeed trip device. This model is an energize-to-trip version of the Woodward ProTech 203 series. It uses three individual speed-sensing units in a two-out-of-three voting configuration to continually monitor prime mover speed for overspeed conditions. Each of these three units has its own power supply and a voltage input of 220 Vac.

The two-out-three hardware voting method and module design of model 8200-210 make it an ideal choice for overspeed monitoring and protection. Normal operations can be sustained with only two of the three units while the third is tested, replaced, or in the event, a single unit is tripped.

Each speed-sensing unit displays its actual current speed and has its own set of LED indicators. These indicators will show if a unit has tripped (there is also a separate alarm output for this), if there is a failure of any unit’s magnetic pickup or its wiring, or if there is an error in the unit’s CPU functioning.
Additional features of the 8200-210 are the ability to reset the system from a remote location, key lock access for programming and testing, and the ability for this system to be configured for compatibility with multiple combinations of power sources.
Product Description

The ProTech 203 Overspeed Protection System is a series of digital overspeed trip devices. This series has several models for various voltage input and trip relay needs. Model 8200-209 is a 120 Vac/dc input, de-energize-to-trip model in this Woodward series. With correct configuration, this system can be compatible with different combinations of power sources.

Through three individual magnetic pickups (MPUs), this device samples prime mover speed every 5 ms. The 8200-209 system actuates its relay output based on a two-out-of-three hardware vote, completed with three identical speed-sensing units, each performing its own speed calculation. Although these individual units are connected to provide this hardware vote, the system is designed to continue operations with only two units online.
