Woodward 8280-465 数字速度控制器 用于变速应用
【产品详情】
8280-465 是伍德沃德 723PLUS 系列数字速度控制器中的高压(90 至 150 Vdc,标称值 22 A)型号。该型号旨在用于变速应用,以控制往复式发动机的速度。还提供低压版本(部件号 8280-465;18-40 Vdc,标称 7 A)。
723PLUS 控制器具有双速信号输入。这些输入可用于两个MPU,前提是速度输入频率在400 Hz至15 kHz范围内。或者,可以改用两个接近开关。在这种情况下,速度输入频率范围应为 30 Hz 至 15 kHz。
此型号的其他 I/O 包括:
- 离散输入(10 ms ±15% 响应时间)
- 模拟输入(±5 Vdc 或 0–20 mA)
- 负载均分输入(满量程精度的 1.0%)
- 0–1 或 4–20 mA 模拟输出
- 0–20 或 0–200 mA 模拟输出
- 继电器触点输出

【英文介绍】
The 8280-465 is the high voltage (90 to 150 Vdc, nominal 22 A) model in the Woodward 723PLUS series of digital speed controllers. This model is intended for variable speed applications to control the speed of a reciprocating engine. Low-voltage versions are also available (part number 8280-465; 18-40 Vdc, nominal 7 A).
The 723PLUS controller has a two-speed signal input. These inputs can be used for both MPUs, provided the speed input frequency is in the range of 400 Hz to 15 kHz. Alternatively, two proximity switches can be used instead. In this case, the speed input frequency range should be 30 Hz to 15 kHz.
Other I/ OS on this model include:
Discrete input (10 ms ±15% response time)
Analog input (±5 Vdc or 0-20 mA)
Load sharing input (1.0% full scale accuracy)
0-1 or 4-20 mA analog output
0-20 or 0-200 mA analog output
Relay contact output
For more information, see the 723PLUS digital speed control for reciprocating engines, Woodward Product Specification 03203, and other manuals on our website that contain more information about 8280-465 I/O and other control specifications, including compliance details.
