8200-202 独立速度感应单元组成 监控原动机速度

【产品详情】

8200-203 Woodward ProTech 203 由三个相同的独立速度感应单元组成，可连续监控原动机速度，并在检测到超速情况时激活跳闸继电器。

伍德沃德的ProTech 203超速保护系列提供两个版本：断电跳闸和通电跳闸。8200-203 型是断电跳闸版本的 120 Vac/dc 输入型号。该型号由三个独立的、相同的速度感应单元组成，每个单元都有自己的电源。这些单元通过磁性拾音器检测原动机速度并执行单独的速度计算，然后将其用于三分之二的硬件投票。

8200-203 型具有丰富的功能集，包括远程复位、LED 性能指示灯、内置自检、报警输出和钥匙锁。

LED 性能指示器位于设备的前面板上，旁边是触摸板和数字显示屏。LED 和数字显示屏共同提供 8200-203 系统当前功能状态的快速、清晰概览。

内置自检功能通过内置频率发生器实现。此设置允许在原动机保持在线的同时测试单个单元。在测试一个单元期间，完全控制由另外两个单元承担。这种配置还意味着，如果有人在 8200-203 上的速度感应装置发生故障，可以在几乎不需要停机的情况下进行更换。

伍德沃德 ProTech 203 超速保护型号 8200-203 的附加功能和说明可在该公司的系列手册中找到：安装和操作手册 85205 （F）。

【英文介绍】

The 8200-203 Woodward ProTech 203 consists of three identical independent speed sensing units that continuously monitor the prime mover speed and activate the trip relay when overspeed conditions are detected.

Woodward's ProTech 203 overspeed protection series is available in two versions: power trip and power trip. Model 8200-203 is a power trip version of the 120 Vac/dc input model. The model consists of three separate, identical speed sensing units, each with its own power supply. These units detect the prime mover speed through magnetic pickups and perform a separate speed calculation, which is then used for two-thirds of the hardware voting.

Model 8200-203 has a rich feature set including remote reset, LED performance indicator, built-in self-test, alarm output and key lock.

The LED performance indicator is located on the front panel of the device, next to the touchpad and digital display. Together, the LED and digital display provide a quick, clear overview of the current functional status of the 8200-203 system.

The built-in self-check function is implemented through the built-in frequency generator. This setting allows individual units to be tested while the prime mover remains online. During testing one unit, full control is assumed by the other two units. This configuration also means that if someone's speed sensing unit on the 8200-203 fails, it can be replaced with little downtime.

Additional features and instructions for the Woodward ProTech 203 Overspeed protection Model 8200-203 can be found in the company's series manual: Installation and Operation Manual 85205 (F).
