Hardware required for SBC

● Safe Brake Relay
The command for releasing or applying the brake is transferred to the Motor Module /
Power Module via DRIVE-CLiQ. The Motor Module / Safe Brake Relay then carries out
the action and appropriately activates the outputs for the brake.

● Safe Brake Adapter
The brake cannot be directly connected to the Motor Module in the chassis format. The
connection terminals are only designed for 24 V DC with 150 mA; the Safe Brake Adapter
is required for higher currents and voltages.
Note
Additionally required hardware for other formats
A Safe Brake Relay is also required for the "Safe Brake Control" in the blocksize format.
With the chassis format (article numbers ending ...3 or higher), a Safe Brake Adapter is
required. The Safe Brake Adapter is available for a 230 V AC brake control voltage.
