不同应用程序，有不同的 I/O系统可以使用： 

*  用于Profibus协议的S800远程 I/O。 同时提供用于安全应用程序的SIL标准模块。 

*  用于本质安全应用程序 (Ex)的S900远程 I/O。也可在非危险区使用。S900 通过Profibus进行连接。 

*  当使用Rack CPU，或与AC 800F一同使用时（Rack CPU被AC 800F取代），或要求有SoE功能时，Rack I/O 适用

S800 I/O 简介

S800 I/O是一个全面的、分布式且模块化的I/O系统，通过工业标准的现场总线与主控制器进行通讯。S800 I/O具有宽范围的连通性，可以连接ABB或其他公司的多种控制器。

Different applications have different I/O systems that can be used:

* S800 remote I/O for Profibus protocol. SIL standard modules for security applications are also available.

* S900 remote I/O for intrinsically secure applications (Ex). It can also be used in non-hazardous areas. The S900 is connected via Profibus.

* Rack I/O is applicable when a Rack CPU is used, or used in conjunction with the AC 800F (the Rack CPU is replaced by the AC 800F), or when SoE functionality is required

Introduction to the S800 I/O

The S800 I/O is a comprehensive, distributed and modular I/O system that communicates with the host controller via an industry-standard fieldbus. The S800 I/O has a wide range of connectivity and can be connected to a variety of controllers from ABB or other companies.
