Safe Brake Adapter SBA

The Safe Brake Adapter SBA is required to implement a Safe Brake Control (Safety Integrated function "SBC") in conjunction with Motor Modules and Power Modules in chassis format.

The Safe Brake Adapter is available for a 230 V AC brake control voltage.

Дизайн



The Safe Brake Adapter SBA has the following connections and interfaces:

  • 1 connection for controlling and transferring feedback from the integrated safety relay (X11)
  • 1 connection for controlling the motor brake coil (X14)
  • 2 connections for supplying power to the brake, either via 24 V DC (X13) or 230 V AC (X12)
  • 1 connection for quick de-excitation of the operating coil (X15)

The Safe Brake Adapter is designed for attachment to a support rail in accordance with EN 50022

Интеграция



The control and feedback signal regarding the switching state of the SBA relay is implemented via terminals of the Control Interface Module (CIM) in the Motor Module/Power Module. The excitation coil of the holding brake is connected directly at the SBA.

For SINAMICS S120, the brake supply voltage must be externally supplied at the SBA.
