Functional Characteristics

1. Integrated Power Supply + Backplane Design

   Integrates AC/DC power converter and RXM extended I/O backplane into one unit, eliminates separate power supply and rack wiring, simplifies system installation and wiring layout.
2. Full TMR Redundant Power Architecture

   Adopts triple independent redundant power conversion channels with 2oo3 voting logic. Single power channel fault completes automatic isolation and failover without system power outage, eliminates single-point power failure risk.
3. High-Stability Isolated Power Output

   Provides clean low-ripple 24VDC field power and 5VDC logic power, fully isolates high-voltage AC input from safety DC control system, prevents electromagnetic interference and fault voltage intrusion.
4. Multi-Level Complete Circuit Protection

   Equipped with overvoltage, overcurrent, short-circuit, reverse polarity and surge protection, fully protects internal power circuits, backplane and connected I/O modules from fault damage.
5. Real-Time Power Status Diagnosis & Indication

   Integrates input voltage monitoring, output current monitoring, temperature monitoring and fault self-diagnosis. Front panel includes POWER OK, INPUT FAULT, OUTPUT FAULT, OVERTEMP LED indicators; fault data uploads to Tricon main controller in real time for alarm and safety interlock.
6. Full Compatibility with Tricon Ecosystem

   Perfectly matches all Tricon digital input/output, analog input/output, communication and remote extension modules; completely retains original TMR safety integrity, diagnosis and fail-safe functions.
7. High-Reliability Industrial Heavy-Duty Structure

   Adopts heavy-duty steel enclosure, anti-vibration, anti-corrosion and dustproof design, supports 24-hour continuous stable operation in harsh industrial sites.
