9905-979 封闭式独立速度感应单元 激活跳闸继电器
【产品详情】
Woodward ProTech 203 型号 9905-979 带有三个相同的封闭式独立速度感应单元，用于监控原动机速度和激活跳闸继电器
Part 9905-979 是一款超速保护器件，在工作温度范围内具有 0.05% 点 + 2 Hz 的精度等级。这是一种断电跳闸系统，使用三个磁性拾音器（MPU）持续监控原动机速度。系统是否激活跳闸继电器基于三个单独的计算，这些计算被置于硬件三分之二的投票中。这些计算由三个相同的速度感应单元执行。
该部件由伍德沃德制造，作为该公司ProTech 203超速保护系统系列的一部分。该系列器件提供多种电源选项。9905-979 是 120 Vac/dc 型号;所有三个单元都有自己的 120 Vac/DC 电源。
该系统的设计，包括单个电源，允许原动机在以下情况下保持在线：
单个速度感应单元的测试
更换单个单元
一台设备因跳闸继电器而离线
尽管这些单元采用模块化方式，但它们都保存在同一个外壳中。此外壳符合 IP 65 / NEMA 4 标准。它被锁定以防止未经授权访问程序模式和单元测试功能。有关编程的更多信息，请参阅ProTech 203手册85195。

【英文介绍】
Woodward ProTech 203 Model 9905-979 comes with three identical enclosed independent speed sensing units for monitoring prime mover speed and activating trip relays
The Part 9905-979 is an overspeed protection device with an accuracy rating of 0.05% point + 2 Hz over the operating temperature range. This is a power-off trip system that uses three magnetic pickups (MPUs) to continuously monitor the prime mover speed. Whether the system activates the trip relay is based on three separate calculations that are placed on a two-thirds vote of the hardware. These calculations are performed by three identical speed sensing units.
The part was manufactured by Woodward as part of the company's ProTech 203 overspeed protection system family. This family of devices offers a variety of power supply options. The 9905-979 is a 120 Vac/dc model; All three units have their own 120 Vac/DC power supply.
The design of the system, including a single power supply, allows the prime mover to remain online under the following conditions:
Test of a single speed sensing unit
Replace a single unit
A device is offline due to a tripping relay
Despite the modular approach of these units, they are all kept in the same enclosure. This enclosure is IP 65 / NEMA 4 compliant. It is locked to prevent unauthorized access to program patterns and unit test functionality. For more information on programming, see ProTech 203 manual 85195.
