Functional Characteristics

1. 16-Channel Commoned Interposing Relay Isolation Output

   Adopts integrated relay isolation structure, completely isolates internal TMR safety controller circuits from field high-power inductive loads, eliminates load inductive interference and reverse electromotive force damage to system modules.
2. Dual Redundant Power Supply Input Design

   Equipped with independent main power and redundant power input terminals; automatic power failover ensures uninterrupted relay operation when single power supply fails.
3. Per-Channel Independent Fuse Protection

   Each output channel configures exclusive fast-acting fuse with visible blown-fuse indication; single channel short-circuit fault completes isolated protection without affecting other channels and entire system operation.
4. Integrated Output Loop-Back Diagnosis Function

   Built-in full-channel loop-back detection circuit, realizes real-time monitoring of relay contact status, load connection status and circuit integrity; fault status transmits to Tricon controller for alarm and safety interlock actions.
5. Perfect TMR Safety System Compatibility

   Fully adapts to Tricon TMR triple modular redundancy voting logic, completely retains original system diagnosis, fault supervision and fail-safe functions after external termination connection.
6. High-Reliability Anti-Loosening Terminal Structure

   Industrial heavy-duty screw terminals maintain stable wiring contact under long-term industrial vibration conditions, prevents signal interruption and poor contact faults.
7. Centralized Wiring & Easy Maintenance

   Unified terminal numbering and centralized wiring layout realize intuitive on-site inspection, rapid fault troubleshooting and convenient maintenance operations.
