Safe Brake Adapter SBA Siemens

Обзор



For SINAMICS S120, S150, G130 and G150 units, a Safe Brake Adapter SBA is required to safely control a motor holding brake via the Safe Brake Control (SBC) safety function according to IEC 61800-5-2.

The Safe Brake Adapter is available for 24 V DC and 230 V AC brake control voltages.

It can be ordered as supplementary component for SINAMICS S120 Chassis Format Units as well as for SINAMICS G130 Chassis Units.

It is available as option (K88, K89) for SINAMICS S120 Cabinet Modules and SINAMICS S150 or G150 Cabinet Units.

Note: The SBA approval is currently only valid for IEC regions (still open for UL regions).

Интеграция



The SBC function is controlled and monitored by the SINAMICS Drives firmware. The control and feedback signal regarding the switching state of the SBA relay is realized via terminals of the Control Interface Module (CIM). The excitation coil of the holding brake is connected directly at the SBA.

For SINAMICS G130 chassis units and SINAMICS S120 Chassis Format Units, the brake supply voltage must be connected externally at the SBA.
