SIL/PL Certified
SRW safety relays achieve SIL3 / PL e with redundant contact architecture and monitoring diagnostics.
Safety & Signaling
SRW safety relays, emergency-stop devices, and LED signaling solutions designed for machine safeguarding.
WEG safety components help machine builders and end users meet EN ISO 13849 and IEC 62061 requirements. Combine SRW safety controllers, emergency stops, guard switches, and signaling towers with detailed documentation and validation support from Gross Automation.
Key Differentiators
Rapid Deployment
Pre-packaged emergency-stop stations and modular signaling towers reduce build time and wiring effort.
Integrated Diagnostics
Safety relay status LEDs and optional communication provide clear feedback for troubleshooting.
Comprehensive Accessories
Guard locking actuators, enabling switches, and stack light modules cover complete safety zones.
