Product Performance
- High safety level control: Reaching SIL 3 and PLe safety levels, dual-channel redundant design ensures single fault does not affect system functions, with probability of dangerous failure (PFH) ≤1×10⁻⁹/h, meeting safety requirements of high-risk industries.
- Fast hazard response: Completes logic judgment and drives output within 5ms after input signal change, which can quickly cut off equipment in hazardous areas in emergency situations, minimizing accident consequences.
- Wide signal compatibility: Supports 8 safety input signals (including emergency stop, safety door, light curtain, etc.), 4 relay outputs can directly control contactors, valves and other actuators without additional conversion components.
- Stable environment adaptation: Maintains logic operation accuracy within -20°C to +60°C, vibration resistance complies with IEC 60068-2-6 standard, adapting to complex vibration environment in factories.
- Convenient maintenance features: Supports online hot-swap replacement, module status is displayed in real time through LED indicators (running/fault/redundancy), and can be remotely diagnosed with Safety Manager software, reducing fault troubleshooting time to within 15 minutes.
