>>>>>型号:8200-1302 数字调速器 充当图形界面和键盘
【功能描述】
8200-1302 是可用于控制汽轮机的几款伍德沃德 505 数字调速器之一。该操作员控制面板充当图形界面和键盘，允许对涡轮机进行调整并与之通信。这可以通过位于设备上的 Modbus 通信端口进行配置。
8200-1302 具有多种可用功能：
热启动和冷启动的自动启动顺序，具有温度输入选项
三速频段的临界速度规避
10 个外部报警输入
10 个外部 DI 跳闸输入
具有相关 RTC 时间戳的跳闸和报警事件的跳闸指示
双速度和负载动态
超速跳闸的峰值速度指示
零速检测
远程压降
频率死区
该装置还提供三种正常工作模式，包括配置、操作和校准模式。
该装置包括两个冗余速度输入，可以接受磁性拾取装置、涡流探头或接近探头。它具有模拟输入 （8），可针对 27 种功能中的任何一种进行配置。该装置还具有额外的 20 个触点输入。这些触点中的前四个触点默认用于关断、提高速度设定点、复位和降低速度设定点。其他的可以根据需要进行配置。此外，该装置还具有两个 4-20 mA 控制输出和八个 Form-C 继电器触点输出。
8200-1302 的前面板包括一个紧急跳闸键、一个退格/删除键、一个 shift 键，以及视图、模式、ESC 和 Home 键。它还具有导航十字键、软键命令和四个 LED，用于关联控制和硬件的状态。

【英文介绍】
The 8200-1302 is one of several Woodward 505 digital governors available to control steam turbines. The operator control panel acts as a graphical interface and keyboard, allowing the turbine to be adjusted and communicated with. This can be configured via a Modbus communication port located on the device.
The 8200-1302 has a variety of functions available:
Automatic start sequence for hot start and cold start, with temperature input option
Critical speed evasion in the three-speed band
10 external alarm inputs
10 external DI trip inputs
Trip indication with associated RTC time stamps and alarm events
Dual speed and load dynamics
Peak speed indication of overspeed trip
Zero speed detection
Long range voltage drop
Frequency dead zone
The unit also offers three normal operating modes, including configuration, operation and calibration modes.
The device includes two redundant speed inputs and can accept a magnetic pickup device, eddy current probe, or proximity probe. It has analog inputs (8) and can be configured for any of the 27 functions. The device also has an additional 20 contact inputs. The first four of these contacts are used by default to turn off, raise speed setpoints, reset, and lower speed setpoints. Others can be configured as needed. In addition, the unit has two 4-20 mA control outputs and eight Form-C relay contact outputs.
The front panel of the 8200-1302 includes an emergency trip key, a backspace/delete key, a shift key, as well as the view, Mode, ESC, and Home keys. It also has navigation cross keys, soft key commands, and four leds to correlate the state of the control and hardware.
For more information on the use and installation of the 8200-1302, see Woodward's original documentation.
