Allen-Bradley 20-750-S | Safe Torque Off (STO) Safety Option Module for PowerFlex 750-Series Drives
Overview
The Allen-Bradley 20-750-S is a Safe Torque Off (STO) module designed for PowerFlex 750-Series drives. It provides a safety-rated method to disable the drive’s output by removing power from the IGBT gate firing circuits, preventing the output devices from switching and producing torque in the motor. This option enhances personnel and machine safety without the need to remove power from the drive itself.
Key Features
-
Functionality: Disables the drive's gate firing circuits (IGBTs)
-
Prevents Motor Movement: Stops drive output from generating AC power to the motor
-
Safety Integrity: Meets SIL 3, PL e, Category 3 safety requirements
-
Drive Compatibility: PowerFlex 753 and PowerFlex 755 drives
-
Minimal Downtime: No need to remove drive main power to ensure safety
-
Compact Design: Installs easily inside the drive
-
Enhanced Safety Compliance: Certified for machine and personnel safety applications
Technical Specifications
-
Catalog Number: 20-750-S
-
Drive Series: PowerFlex 750-Series (753 and 755)
-
Safety Ratings: SIL 3 (IEC 61508), PLe (ISO 13849-1), Category 3
-
Primary Function: Safe Torque Off disabling of IGBT firing circuits
-
Installation: Internal to the drive
-
Operating Temperature Range: Matches drive specifications
-
Certifications: UL, CE, TÜV, CSA
Applications
-
Industrial machinery requiring safe maintenance access
-
Robotics and automated assembly lines
-
Material handling systems
-
Packaging equipment
-
Any application needing functional safety without power cycling
Why Choose the 20-750-S?
-
Safety Without Shutdown: Maintains power to the drive while safely disabling motor torque
-
Certified Protection: Meets the highest safety standards
-
Easy Integration: Designed specifically for PowerFlex 750-Series drives
-
Minimizes Downtime: Quick recovery after safety events
-
Reliable Operation: Trusted performance for industrial safety-critical systems
