ABB FSPS-21 PROFIsafe module

ABB is providing integrated safety functionality for its all-compatible variable speed drives (VSDs) to simplify the engineering design process in machine manufacturing and automation. The plug-in PROFIsafe module (FSPS-21) removes the need for external safety components and reduces the need for configuration.

The FSPS-21 enables safe machine control and seamless safety communications between the drive and the PLC in a wide range of machines from conveyors to grinders. This is enabled through the PROFIsafe over the Profinet I/O communication protocol.

The module allows for control, safety and PC tool communication to the drive through one Ethernet cable, which simplifies installation and commissioning. The module simplifies commissioning because it requires no additional safety configuration in the drive and moreover reduces the need for training.

The FSPS-21 module is TÜV Nord certified and is compatible with ABB ACS380 machinery drives, ACS580 general-purpose drives and ACS880 industrial drives. The module offers Safe Torque Off (STO) and Safe Stop 1-time controlled (SS1-t) safety functions. It achieves SIL 3/PL e and is therefore suitable for demanding applications.
