2301D 8273-501数字负载分配和速度控制单元

产品说明

伍德沃德公司的8273-501理号被指定为2301D数字负载分配和速度控制单元之一。

8273-501是设计用于连接和安装到普通、非危险位置的型号之—。

这种2301D型设计有一个微处理器作为基本组件，使该单位的运作，以完成其功能。该装置配有标准硬件组件，包括一个负荷传感器、一个致动器驱动器、一个微处理器速度传感器。还有一对可配置的模拟输入和可配置的模拟输出。还有一组8个离散开关输入(其中3个可配置)，以及4个可配置的离散继电器驱动器输出。

发动机和发电机速度需要同步，并且在每分钟90到3600转的范围内。在额定转速下，电磁拾波器提供的频率需要在100到20，000赫兹的范围内。8273-501上可用的通信端口有RS-232、RS-422、9针连接器以及1200至38，400波特，全双工。

8273-501安装有独特的算法，能够通过使用负载脉冲和负载拒绝逻辑应用程序来增强速度控制瞬态响应能力。所需的标准电源输入为18至40伏直流电。该设备在我们的自动保护保修范围内。

Product description

Woodward 8273-501 is designated as one of the 2301D digital load distribution and speed control units.

The 8273-501 is one of the models designed for connection and installation into ordinary, non-hazardous locations.

This type 2301D design has a microprocessor as the basic component that enables the unit to operate in order to complete its functions. The unit comes with standard hardware components, including a load sensor, an actuator driver, and a microprocessor speed sensor. There is also a pair of configurable analog inputs and configurable analog outputs. There is also a set of eight discrete switching inputs (three of which are configurable), and four configurable discrete relay driver outputs.

Engine and generator speeds need to be synchronized and in the range of 90 to 3600 RPM. At the rated speed, the frequency provided by the electromagnetic pickup needs to be in the range of 100 to 20,000 Hz. Communication ports available on the 8273-501 are RS-232, RS-422, 9-pin connectors, and full duplex from 1200 to 38,400 baud.

The 8273-501 is equipped with a unique algorithm that enhances speed control transient response through the use of load pulse and load rejection logic applications. The standard power input required is 18 to 40 volts DC. The equipment is covered by our automatic protection warranty.
