10.2. Series connection with Y-distributors
The series connection is shown here based on the example of the version with plug connector M12. The key adapters are
connected one behind the other with the aid of pre-assembled connecting cables and Y-distributors. The safety outputs are
switched off if the key is removed from the key adapter or if an error occurs on one of the key adapters.
10.2.1. Maximum cable lengths
Important!
The maximum number of devices in a BR switch chain depends on many factors, including the cable
length. This case example shows a standard application. You will find further connection examples at
