The 20-750-S3 module is an advanced integrated safety solution designed for Allen-Bradley PowerFlex 755/755T series drives, featuring the essential Safe Torque Off (STO) function to prevent unauthorized motor operation. This module supports both networked and hardwired STO commands, with network control facilitated via Ethernet and orchestrated by a safety controller linked to the drive. Operating on a 24 Volts DC supply from PELV or SELV sources, the module incorporates current sinking inputs and stringent electrical specifications for enhanced safety. Its compliance with UL, CE, C-Tick, and TUV standards underscores its reliability and broad acceptance, and it requires protective measures against conductive contamination, such as IP 54-rated enclosures or a controlled environment.
