Information About 20-750-S4
The 20-750-S4 is part of the Allen-Bradley PowerFlex 755 family, offering advanced drive-based safety functions for critical motor control applications. It enables STO, timed SS1, monitored SS1, and safe brake control, with support for controller-based safety through GuardLogix 5580 and Compact GuardLogix 5380 controllers. Designed as a current sinking input module, it operates with on-state voltages between 11–30V DC, off-state voltages of -3 to 5V DC, and features a fast input reaction time of less than 10 ms. The module removes power from drive output devices to safely disconnect motor torque, providing compliance with IEC 61508 and SIL-rated safety requirements. While it ensures safety disconnection, it is not intended as a control option for frequent drive start/stop operations. Certified by UL, CE, TÜV, and C-Tick, the 20-750-S4 integrates seamlessly with PowerFlex 755/755T drives for reliable safety compliance in automation environments.
Key Features:
- Safety functions: Provides Safe Torque Off (STO), timed SS1, monitored SS1, and safe brake control for compliant motor safety.
- Compatibility: Designed for PowerFlex 755 and 755T drive platforms, with GuardLogix 5580 and Compact GuardLogix 5380 controller integration.
- Input type: Current sinking inputs with defined electrical ranges for stable safety performance.
- Electrical characteristics: Operates with on-state voltage of 11–30V DC, off-state range of -3 to 5V DC, minimum on-state current 2 mA, maximum off-state current 1.5 mA.
- Reaction speed: Input reaction time under 10 ms for rapid safety response.
- Standards compliance: Certified by UL, CE, TÜV, and C-Tick for global safety approvals.
- Application scope: Ensures safe motor torque removal in compliance with IEC 61508 and SIL standards.
- Operational precaution: Not recommended as a routine start/stop control method due to potential residual mechanical forces.
- Integration: Works seamlessly with other Allen-Bradley safety devices in automated systems.
The 20-750-S4 delivers the reliability and precision required for drive-based safety, ensuring compliance and protection in Allen-Bradley PowerFlex 755/755T systems.
