8262-092 数字控制装置 控制系统
【产品详情】
该数字控制装置是伍德沃德调速器的 723 位置控制系统的一部分。型号 8262-092 提供 20-160mA 执行器输出。723 位置控制器也可用于 4-20mA 执行器输出(型号 8262-094)。
8262-092 型号通过在涡轮机控制故障时提供执行器输出信号来保护涡轮机系统免受超速情况的影响。723 型号 8262-092 设计用于与伍德沃德 505 数字涡轮机控制配合使用。如果发生 505 控制故障,723 位置控制将自动接管作为执行器信号源。
如果执行器信号源从 505 控制器切换到 723 控制器,则执行器输出信号在切换后手动升高或降低。当 505 控制功能恢复时,执行器信号源从 723 控制切换回来。
有一些附件可以与 8262-092 控制器一起使用。部件号 9907-205 是伍德沃德的手持式编程器,它插入此位置控制器的串行端口 J1 以调整和监控其功能。723 位置控制器也可以使用可选面板 723 操作板进行操作。有关将这些附件与本机一起使用的详细信息,请参阅伍德沃德 723 安装和操作手册 26097。

【英文介绍】
The digital control is part of Woodward's 723 position control system. Model 8262-092 offers 20-160mA actuator output. The 723 position controller is also available for 4-20mA actuator outputs (Model 8262-094).
Model 8262-092 protects the turbine system from overspeed conditions by providing an actuator output signal in the event of a turbine control failure. The 723 model 8262-092 is designed for use with the Woodward 505 digital turbine control. If a 505 control failure occurs, the 723 position control automatically takes over as the actuator signal source.
If the actuator signal source is switched from the 505 controller to the 723 controller, the actuator output signal is manually raised or lowered after the switch. When the 505 control function is restored, the actuator signal source switches back from the 723 control.
There are some accessories that can be used with the 8262-092 controller. Part number 9907-205 is Woodward's handheld programmer that plugs into serial port J1 of this location controller to adjust and monitor its functionality. The 723 position controller can also be operated using the optional panel 723 operation board. For more information about using these accessories with the unit, see Woodward 723 Installation and Operation Manual 26097.
