从站也分为两种，一种是带有as-interface通信芯片的智能传感器/执行器，另一种是分离型i/o模块连接普通的传感器/执行器。在智能型装置中，集成有通用的asic(as-i专用集成电路)，有自己的从站地址。它们可以通过电缆直接连接到as-i中，并具有诊断功能；例如图1中的逻辑模块logo!、电机启动器等。对于普通i/o设备来说，如果想接入as-i系统，必须提供一个带有asic的as-i模块，i/o设备与这些模块连接，如图4中的i/o模板，传感器、执行器、开关等元件直接通过电缆插接到模板上即可。
标准的AS-I节点(从站)地址为5位二进制数，每个标准从站占一个AS-I地址，最多可以连接31个从站。在最新的as-i总线技术规范2.1版本中，一个主站所能控制的从站数量由31个增加到62个，每个地址连接2个从站(分为a\b组)。
3.3供电单元
AS-I 电源是AS-I网络的一个组成部分。它们提供系统的电子设备(as-i模块和 as-i 主站)和连接的传感器技术。而且，AS-I电源的集成数据解耦可以确保数据和电能分隔，因此使AS-I能够在一条线路上传输数据和电源，普通标准电源不适合。AS-I网络的电源模块的额定电压为dc24v，为31个从站的最大电流为2a；如果从站带动的某个执行器功率较大,所需电流大于65ma时,则必须外接辅助电源。它的连接方式可由图2知 。
