Woodward 8280-422 数字速度控制器  具有多种控制功能

【产品详情】

8280-422 是一种数字速度控制器，设计用于低速（低于 100 rpm）柴油发动机。伍德沃德数字速度控制器还有另一个版本，型号为 8280-423，专为中高速发动机（超过 100 rpm）而设计。

这款 723PLUS 数字船用速度控制器适用于需要单元离合器和机械负载分配的双引擎船用应用。在这些应用中，8280-422 将调节柴油发动机的速度和负载。

723PLUS 型号 8280-422 具有多种控制功能。这包括多种燃油限制功能，例如启动燃油限制、扭矩燃油限制以及歧管或外部燃油限制。软加载/卸载、离合器控制和允许逻辑、弹性联轴器扭转滤波和单节气门操作只是该控制中包含的功能的更多示例。伍德沃德 723PLUS 手册 02881 包含每个功能的完整功能和详细信息列表。

手册 02881 还包含有关 8280-422 I/O 的完整信息，其中一些是可配置的。一些输入是双速感应输入，可用于MPU或接近开关;八个离散输入;和两个冗余通信端口。输出包括三个可配置的 4–20 mA 输出、两个可配置的报警继电器、一个支持手持编程器的串行端口和一个 0–200 mA 执行器输出等。

【英文介绍】

The 8280-422 is a digital speed controller designed for use in low speed (less than 100 rpm) diesel engines. There is another version of the Woodward digital Speed controller, model 8280-423, designed for medium to high speed engines (over 100 rpm).

The 723PLUS digital Marine speed controller is suitable for twin-engine Marine applications that require a unit clutch and mechanical load distribution. In these applications, the 8280-422 will regulate the speed and load of the diesel engine.

The 723PLUS model 8280-422 has a variety of control functions. This includes a variety of fuel limiting features such as starting fuel limits, torque fuel limits, and manifold or external fuel limits. Soft load/unload, clutch control and allowing logic, elastic coupling twist filtering and single throttle operation are just a few more examples of the features included in this control. The Woodward 723PLUS manual 02881 contains a full list of features and details for each feature.

Manual 02881 also contains complete information about 8280-422 I/O, some of which is configurable. Some inputs are two-speed induction inputs that can be used with MPU or proximity switches; Eight discrete inputs; And two redundant communication ports. Outputs include three configurable 4-20 mA outputs, two configurable alarm relays, a serial port to support a handheld programmer, and a 0-200 mA actuator output.
