Safe Brake Adapter SBA 24 V DC (option K89)

Description
Safe Brake Control (SBC) is a safety function that is used in safety-related applications. In
the no-current state, the brake acts on the motor of the drive using spring force. The brake is
released (opened) when current flows through it (=low active).
The Safe Brake Adapter 24 V DC is installed in the cabinet unit in the factory. An infeed is
connected to terminal -X13 on the Safe Brake Adapter to provide the necessary power. For
control, a connection is established between the Safe Brake Adapter and the Control
Interface Module using a cable harness installed in the factory.
For controlling the brake, on the plant side, a connection must be established between
terminal -X14 on the Safe Brake Adapter and the brake.
Maximum cable length of the brake control
The maximum permissible cable length of 30 m between the Safe Brake Adapter 24 V DC
and the brake must be observed. To accurately calculate the maximum cable length, see
the SINAMICS Low Voltage Engineering Manual on the customer DVD supplied with the
device.
