Product Performance
16 independent configurable safety input channels, supporting two input types: dry contact and PNP, can flexibly adapt to various on-site safety-related digital signal sources with extremely strong versatility
Reaches SIL 3 safety integrity level and complies with IEC 61508 safety standards, which can be directly applied to safety interlock systems in high-risk industrial scenarios to ensure personnel and equipment safety
Supports switching between normal and high-speed response modes, the response time of high-speed mode is ≤0.1ms, which can accurately capture fast-changing safety signals and provide extremely fast signal support for emergency interlock actions
Adopts dual electrical isolation design between safety side and non-safety side, high isolation between channels, combined with industrial-grade enhanced anti-electromagnetic interference circuit, can effectively resist strong electromagnetic radiation and surge impact, ensuring the stability and reliability of safety signal collection
Each channel integrates overvoltage protection and reverse polarity protection, and the module level adds surge protection, which can effectively prevent damage to the module caused by on-site wrong wiring, voltage fluctuations and external interference, extending the service life of the module
Equipped with full-link safety fault diagnosis function, real-time monitoring of channel working conditions, isolation status, module operation and communication status, fault information is uploaded to the controller safety core in real time, facilitating operation and maintenance personnel to quickly locate and handle potential safety hazards
Wide operating temperature range of 0℃ – 60℃, industrial-grade rugged packaging design, can long-term stable operation in complex industrial sites with high temperature, high humidity and multiple interferences, with strong environmental adaptability
Deeply compatible with the ABB AC 800M series safety control system, plug-and-play, supporting online configuration debugging and parameter configuration, simplifying safety system integration and maintenance processes, reducing operation and maintenance costs
High-reliability design, MTBF ≥3,500,000 hours, fully meeting the rigorous requirements of 24-hour uninterrupted operation in industrial safety sites
