The Allen-Bradley 20-750-S3 module is a sophisticated integrated safety component designed specifically for PowerFlex 755/755T series drives, offering essential Safe Torque Off (STO) functionality. This module enables networked or hardwired STO commands, utilizing an Ethernet cable and a safety controller to secure operations against unauthorized motor activity, crucially supporting maintenance by allowing mechanical work without affecting electrical safety. With a requirement for a 24V DC power supply (PELV/SELV), it handles input voltages from 11 to 30 Volts DC and supports environmental protection through IP 54 compliant enclosures, backed by UL, CE, C-Tick, and TUV certifications for reliable, certified safety performance.
