Schlegel ASI Interface Bus System


Used for networking the Schlegel control units and pilot lights (control devices, operator consoles, panels...) to the most common Fieldbus systems (such as AS-Interface, CANopen, Profibus DP, ...).
The Fieldbus compatible Schlegel control units are particularly for applications using a large number of control units and pilot lights to be connected to the Fieldbus at less wiring effort.
