Extending Communication
If an installation requires more than one DIN rail, connect the Communication
Supply (CS) and Communication Data (CD) terminals from the P1 BIM to the
same terminals on the first device of every additional DIN rail (a TX-I/O Power
Supply or Bus Connection Module). TX-I/O Power Supplies and Bus Connection
Modules include a second set of CS and CD contacts to simplify connection of
additional DIN rails. Ensure that the system neutral is installed.
NOTE:
Maximum extension of the TX-I/O bus is 50 meters total for all devices.
