Signal distribution board

EtherCAT 插拔式模块能够直接安装在电路板上。专用的电路板（信号分配板）给各个特定应用的连接器分配信号和电源，以便根据需要将控制器连接至其它设备模块。

EJ 入门套件

倍福 EJ8906-0005 入门套件可以帮助机械工程领域的客户快速了解即插即用生产流程。入门套件包含一个预定义的电路板（信号分配板），各个外形尺寸的 EtherCAT 插拔式模块对应的插槽，以及用于整合电缆线束的配套连接器。

Beckhoff offers various options for the development and project implementation of an individual signal distribution board:

Easy to integrate into in-house electronics	The customer selects the EJ modules required for the application from the product portfolio. The signal distribution board can be developed by the customer themselves on the basis of a design guide, allowing them to utilize their in-house development capabilities and protect their expertise.
As a customer-specific complete solution on request	Beckhoff offers development and production of signal distribution boards as a service. A service comprising the development phase only is not offered.
Plug-and-work with complete I/O box	Beckhoff offers development and production of an I/O controller box in an IP20 housing as a service.
Plug-and-work with complete control cabinet	Beckhoff provides individual control cabinet concepts from the company’s in-house systems engineering to implement projects quickly and secure a competitive edge. The signal distribution board is integrated directly into the system solution.

图中所示的仅是用来说明功能的信号分配板示例。基本型号只包含基本功能；占位模块用于在模块网段中所有未使用的功能模块占位。

在扩展版本中，会根据功能需要用 EtherCAT 模块取代这些占位模块；它们会因设备的不同而不同（例如，不同类型的电机有不同的反馈模块）。

高配版本提供全系列功能或完整的信号分配板。此外，应用特定的控制系统组件仅在使用 EtherCAT 时才偶尔需要使用。可以使用 EtherCAT 端子模块或 EtherCAT 端子盒选择性地进行扩展。

这个系统特别适用于使用了很多相同 I/O 模块的大批量机器生产应用，可以实现平台概念。
