AS-Interface (AS-i) Fieldbus Digital Network Devices

AS-interface (commonly referred to as AS-I) is a low-level I/O system. It was originally intended to be a simple, low cost system that would be easy to install and maintain. With that philosophy in mind, the original developers designed AS-I as a discrete two wire system. It incorporated features like automatic station addressing, and power and data carried on a single pair of wires.

Today, AS-I can be used as a stand alone network or can be connected to a higher level system, such as DeviceNet, or Profibus-DP, through a gateway. The gateway acts as a slave to the higher system and a master to the AS-I system.

Item Description
Gateways control the field devices on an AS-i network and interface with host control systems and computers.
Power supplies provide the required voltage to the AS-i network.
Asco as-i switch Monitors provide visual, electronic, and digital indication of valve position and device status. Controllers monitor valve position and have an output typically used to drive a solenoid valve.
I/O modules and junction boxes are used to connect field wiring between devices. These devices can also be used to connect conventional devices to an AS-i system.
Cable, cordets, and field wiring connectors specifically designed for ASi systems. Quick-disconnects are used for ease of installation and maintenance.
