Product Performance
The data transmission delay of the fibre optic link is ≤50ms, and the communication delay of the Ethernet port is ≤10ms, meeting the real-time requirements of remote control; the TMR architecture achieves single-point fault tolerance, with a fault switching time ≤10ms, ensuring uninterrupted data transmission when communication is interrupted.
It supports interconnection between controllers and remote I/O modules 12 kilometers away, and a single module can manage 16 channels of mixed signals (digital/analog), adapting to distributed equipment layout scenarios. The online diagnostic module can monitor power abnormalities, link interruptions, module faults and other states, with a diagnostic coverage of ≥99%, and fault information is uploaded to the Triconex system monitoring platform in real time via the communication interface.
The hot-swappable design allows live module replacement without affecting system operation; the industrial-grade wide-temperature and anti-EMC performance ensure stable operation in high-temperature and strong electromagnetic environments, with a Mean Time Between Failures (MTBF) ≥1,000,000 hours (MIL-HDBK-217F, 25℃ environment).
