Product Performance

PMC676TX adopts industrial-grade switch chip and shielded circuit design, maintaining stable operation in the wide temperature range of -40°C to 75°C, meeting the needs of extreme industrial environments. The dual power supply redundant input design ensures uninterrupted switching during power supply interruption, with system availability ≥99.99%.

Gigabit electrical ports support adaptive rate and full-duplex/half-duplex modes, with 12Gbps switching capacity and 8.9Mpps packet forwarding rate, achieving low-latency (≤5μs) data transmission to meet industrial control real-time communication requirements. VLAN and QoS functions can divide network partitions and prioritize key business data scheduling to avoid network congestion.

EMC performance complies with industrial standards, resisting strong electromagnetic interference and pulse impact; the metal housing has electromagnetic shielding capability with common mode rejection ratio ≥100dB. It supports remote network management and fault diagnosis, with Mean Time Between Failures (MTBF) ≥200,000 hours and low maintenance cost.
