ASi Bus Interface
Actuator Sensor Interface. Used to network sensors and actuators. ASi is a two wire interface; Power and Data. Based around ProfiSafe [developed from Profibus DP].ASI bus was developed by Siemens Automation. This is a Unshielded 2-wire [Yellow cable], Unterminated, Ungrounded Sensor Bus. The Topology may be either Bus, Ring, Tree, or Star at up to 100 meters. Power is provided by a 24V floating DC supply, which can supply at least 8 A over the network. The AS-Interface is an open standard based on IEC 62026-2 and EN 50295. The AS Interface may also be termed the 'AS-Interface', 'ASI Bus', or 'ASi-Bus'.
