8290-195 控制模块 作为超速保护器使用

8290-195是一种控制模块、转速控制器、调速器和电源模块。它还可以作为超速保护器使用。它是由美国的伍德沃德公司生产的，该公司拥有130多年的发动机控制器设计和制造经验，并广泛应用于航空、工业发动机、透平和发电控制等领域。
WOODWARD 8290-195是一种12V等时电动调速器 (EPG)控制器，用于柴油机，其速度范围为3000 Hz至6000 Hz，没有启动燃料限制。EPG系统特别适用于没有机械传动或液压油供给的调速器和具有低质量、低摩擦燃油连杆的主动机。EPG Model 512/1712适用于12V系统，Model524/1724适用于24V系统。此外，还提供了四种磁感应频率范围的转速控制器，适用于柴油机和燃气轮机，或汽油和燃气发动机。
8290-195光电编码器是集光、机、电技术于一体的数字化传感器，主要利用光栅行射的原理来实现位移。一数字变换，通过光电转换将输出抽上的机城几何位移量转换成脉冲或数字量的传感器，典型的光电编码器由码盘、检测光栅光电转换电路( 包括光源、光敏器件、信号转换电路)、机械部件等组成。光电编码器具有结构简单、精度高、寿命长等优点，广泛应用于精密定位、速度、长度、加速度.振动等方面。这里我们主要介绍SIMATIC S7系列高速计数产品普遍支持的增量式编码器和绝对式编码器1.2增量式编码器增量式编码器提供了一种对连续位移景离散化、增量化以及位移变化(速度)的传感方法。增量式编码器的特点是每产生一个输出脉冲信号就对应于个增量位移，它能够产生与位移增量等值的脉冲信号，增景式编码器测景的是相对于某个基准点的相对位置增量，而不能够直接检测出编对位置

The 8290-195 is a control module, speed controller, governor and power module. It can also be used as an overspeed protector. It is produced by the Woodward Company in the United States, which has more than 130 years of experience in the design and manufacture of engine controllers and is widely used in aviation, industrial engines, turbines and power generation control.
WOODWARD 8290-195 is a 12V isochronous electric governor (EPG) controller for diesel engines with a speed range of 3000 Hz to 6000 Hz with no starting fuel limit. The EPG system is particularly suitable for governors with no mechanical transmission or hydraulic oil supply and drivers with low-mass, low-friction fuel linkages. The EPG Model 512/1712 is suitable for 12V systems and the Model524/1724 is suitable for 24V systems. In addition, speed controllers are available in four magnetic induction frequency ranges for diesel and gas turbines, or gasoline and gas engines.
The 8290-195 photoelectric encoder is a digital sensor integrating optical, mechanical and electrical technology, which mainly uses the principle of grating line emission to achieve displacement. A digital conversion, through the photoelectric conversion of the output of the machine city geometric displacement into a pulse or digital sensor, a typical photoelectric encoder by the code disk, detection grating photoelectric conversion circuit (including light source, photosensitive devices, signal conversion circuit), mechanical components, etc. The photoelectric encoder has the advantages of simple structure, high precision, long life and so on, and is widely used in precision positioning, speed, length and acceleration. Vibration and so on. Here we mainly introduce the incremental encoders and absolute encoders commonly supported by SIMATIC S7 series high speed counting products. 1.2 Incremental Encoders Incremental encoders provide a method for discretization, increment and displacement change (velocity) sensing of continuous displacement. The characteristic of the incremental encoder is that each output pulse signal is corresponding to an incremental displacement, and it can produce a pulse signal equivalent to the displacement increment. The augmented encoder measures the relative position increment relative to a certain reference point, but cannot directly detect the encoding position
