Wiring without tool
☺ direct simple connection
of sensors/actuators or modules
☺ keyed flat cable protected against reverse polarity
-> data and energy via one cable
☺ isolation displacement technology/piercing -> simple and safe contacting
-> high protection rating IP67,
even after removal of the connection
☺cutting to size and stripping not necessary
☺ problem-free displacement of the connection possible thanks to self-healing cable depending on the type of cable

Operational reliability
Operational reliability
Transmission of data and energy
Each AS-Interface message is monitored in the receiver with regard to parity bit and several other independent values.
This guarantees an extremely high safety for the detection of one or several errors.
A repetition of the message takes 150 µs and is included in the cycle time of 5 ms.
AS-Interface can be used under extreme conditions (e.g. panel mounting, lower ceilings etc.) without any problem.
