FSO-21 ABB Safety Functions Module
KKM Solutions is an independent parts distributor, not an authorized ABB dealer — how we source.
Overview
Part number FSO-21 from ABB, listed in Variable Frequency Drives (VFD). KKM Solutions quotes this part with pricing and availability confirmed per order.
The FSO safety functions module is an option for the ACS880 drives. The Safe torque off (STO) function is a standard feature on the ACS880 drives. The FSO module does not operate the drive; it only monitors the actions of the drive and commands safety functions to be executed. The request for safety functions can come from an external safety system, for example, a push button, a safety PLC, or from an FSO internal fault. Some safety functions can be permanently active. If the drive does not fulfill the commands of the FSO, the FSO shuts down the drive using the Safe torque off (STO) function. If the drive is connected to a safety PLC, the safety of the fieldbus communication can be secured with the PROFIsafe over PROFINET technology. The FENA-21 fieldbus adapter module, communicates with the FSO module. If a pulse encoder is used in the safety system, it is connected to the FSE-31 module, which communicates with the drive and the FSO-21 module. Manufacturer: ABB.
