Product Performance
With high safety level, dual certification of SIL 3 and PLe, it can be directly applied to safety interlock control in high-risk industrial scenarios, fully ensuring the safety of personnel and equipment
Integrates multiple types of input and output channels, distinguishing between safety channels and general channels, which can flexibly adapt to signal collection and control needs of different safety levels with extremely strong versatility
Safety output adopts force-guided relay to ensure no false output in fault state, ensuring the reliability of safety control at the hardware level
Equipped with complete full-link fault diagnosis function, real-time monitoring of channel status, power supply status and internal logic operation, fault information can be intuitively fed back through indicator lights or communication interfaces, facilitating operation and maintenance personnel to quickly locate problems
Wide temperature operating range covering -20℃ – 60℃, industrial-grade rugged housing design, can resist harsh conditions such as on-site electromagnetic interference and vibration, and operate stably for a long time in complex industrial environments
Supports flexible installation methods, adapts to different on-site installation layout needs, and simplifies the installation and commissioning process
Equipped with manual reset function, which can flexibly set reset logic according to on-site safety regulations, improving operational safety and convenience
Compatible with GE industrial control systems and mainstream third-party control systems, supporting multiple communication protocols, facilitating system integration and data interaction
High-reliability design, MTBF ≥4,000,000 hours, fully meeting the 24-hour uninterrupted safety protection needs of industrial sites
