Data and power through a single cable
The abbreviation AS-i stands for Actuator-Sensor Interface. This interface connects the modules in the lowest process level in automation systems with each other. The usual cable trees are replaced here by a single electrical cable – the AS-i cable. This cable carries both data and power.
The four AS-i components
Leading manufacturers around the world support this simple wiring system. It consists of four components: the master, the slaves, a power supply and the yellow AS-i cable. Each slave has a unique address assigned to it which the master uses to exchange in- and output data. Insulation penetration technology means the modules can be quickly and easily attached or moved on the AS-i cable.
Quickly identify and fix errors
Diagnostics units or masters with built-in diagnostic functions make troubleshooting easier. Failed slaves can be quickly identified, replaced and automatically re-addressed by the master.
An all-round good idea
In short: AS-i is a system requiring little installation and maintenance effort, saving time and money. Additionally it is one of the simplest field busses, making its handling possible without specialized knowledge.
