The familiar yellow cable is not just a symbol for the legendary efficiency of AS-Interface, it is also one of the reasons for it. Even its basic geometry offers significant advantages. In contrast to the round cables used in conventional automation systems, no plugs or tees are needed for connecting modules to the AS-i flat cable. This saves not only material but also a great amount of time in installation and documentation – while at the same time providing virtually limitless topological freedom. The following articles deal with the installation technology in IP67.
Linking to AS-i is made by the yellow or the black AS-i profile cable with penetration technology or using the M12 round cable.
The profile cable is available with a conductor cross-section of 1,5 mm² or 2,5 mm².
AS-i together with M12 allows you to use commonly available plugs and cables. The typical conductor cross-sections for M12 cables are less than 0.4 mm².
The conductor cross-section has an affect on the cable protection.
The IP67 modules are suitable as a start or end point of the profile cables. No additional end caps are required. The AS-i/AUX profile cable can begin or end directly in the module (IP54).
AS-i profile cables can be used through a passive distributor in combination with an M12 connector.
The typical topology is a tree structure; stub lines are possible wherever desired.
The optimal installation for any application.
Cable protection against short circuits
- Optional with integrated fuse, either with 4 × 4 A replaceable fuse or with 4 × 1 A self-resetting fuse
- Additional protection for connected devices
- Reliable protection against short circuits

U = R × I
Voltage = Resistance × Current
The longer the AS-i cable, the greater the resistance.
This means for 24 Volt AS-i that a cable length of 50 meters should not be exceeded, since otherwise the voltage could drop too much.
