Features:
- Standard Safe Torque Off option module identified by catalog code 20-750-S.
- Documented for several PowerFlex 750-Series drive families in Rockwell manual 750-UM002.
- Distinct from the XT, Safe Speed Monitor and networked STO option codes.
20-750-S is the standard Safe Torque Off option in the PowerFlex 750 family. Its value in a maintenance plan is the exact option identity, not an assumption that every safety option or drive revision is interchangeable.
Rockwell manual 750-UM002 lists supported PowerFlex 753, 755 and selected 755T drive products. Confirm the actual drive model and revision against the current manual before selecting a spare.
Rockwell currently lists 20-750-S as Active. Any safety-function change requires the site safety assessment, the drive-specific instructions and validation by qualified personnel; this product page is not an installation procedure.
20-750-S | Manufacturer: Allen-Bradley | Product Type: PowerFlex 750 Safe Torque Off Option Module. Apter Power supports exact-model documentation review, quotation and sourcing.

- 20-750-S is the standard Safe Torque Off option in Rockwell publication 750-UM002.
- 20-750-S-XT is a separately listed corrosive-gas-protection variant.
- 20-750-S1 names Safe Speed Monitor; 20-750-S3 names a networked STO option, so the suffix is material.
- Keep a photo of the existing option label and drive nameplate with the spare request.
- Rockwell 750-UM002 lists the applicable PowerFlex 753 and 755 drive families.
- The manual also lists selected 755TL, 755TR, 755TM and 755TS products.
- The drive catalog number, frame and current documentation must be checked together for a replacement plan.
- Do not infer suitability for a drive from a shared PowerFlex 750 family label alone.
- 20-750-S is part of a safety-related drive arrangement, not a complete safety system by itself.
- Use the applicable Rockwell 750-UM002 revision for design, installation, configuration and validation.
- Site safety documentation should identify the installed option and the drive it serves.
- Any change to a safety function belongs with qualified personnel and the approved machine assessment.
- 20-750-S is used where a supported PowerFlex 750 drive has the standard STO option.
- Installed-machine service calls for matching the exact module code and drive record.
- The standard option should be distinguished from XT, Safe Speed Monitor and networked STO variants in procurement.
- Active OEM status allows current sourcing while site-specific safety compatibility still needs engineering review.
