Functional Characteristics

1. Full TMR Fault-Tolerant Safety Architecture

   Three independent output execution channels perform synchronous output and 2oo3 majority voting logic. Single channel fault completes automatic isolation without system shutdown, eliminates single-point failure risk and maintains continuous safe control operation.
2. 16 Independent Isolated Relay Dry Contact Outputs

   Each channel adopts complete relay isolation design, fully isolates field harsh electromagnetic interference and fault voltage from internal safety system, prevents fault propagation between channels and improves output safety stability.
3. Advanced Real-Time Loop-Back Diagnosis Function

   Integrates full-channel contact status detection, load fault detection, short-circuit fault detection, field power loss detection and module self-diagnosis. All fault statuses are displayed by front-panel LEDs and uploaded to Tricon controller in real time for alarm and safety interlock actions.
4. Multi-Level Circuit Protection Design

   Equipped with surge protection, short-circuit protection, overload protection and reverse polarity protection, fully protects module internal circuits and field devices from fault damage.
5. Low-Switching-Frequency High-Reliability Relay Output

   10Hz maximum switching frequency, suitable for long-life safety interlock switching control rather than high-frequency dynamic control, ensures stable contact action and long service life in safety-critical applications.
6. Hot-Swappable & Maintenance-Friendly Design

   Supports online module replacement without powering down the entire safety system, greatly reduces system downtime and maintenance difficulty.
7. Intuitive Status Visual Indication

   Front panel integrated MODULE OK, FAULT, ACTIVE LED indicators and individual channel status indicators, realizes intuitive on-site status monitoring and rapid fault troubleshooting.
