Extreme Temperature Operational Reliability
Engineered for harsh environments, this industrial Ethernet switch operates flawlessly in temperatures ranging from -40°C to +75°C. Its robust design ensures uninterrupted performance in extreme conditions, such as freezing outdoor installations, scorching factory floors, or fluctuating industrial sites, making it ideal for sectors like oil and gas, mining, or transportation where thermal resilience is critical.
Seamless Multi-Gigabit Speed Integration
Featuring auto-negotiation on all four 10/100/1000BASE-T copper ports, the switch intelligently adapts to connected devices, supporting speeds from 10Mbps to 1Gbps. This ensures backward compatibility with legacy hardware while optimizing bandwidth for modern high-speed applications like real-time automation, HD video surveillance, or data-intensive IoT systems—all without manual configuration.
Versatile Copper and SFP Fiber Connectivity
Combining four copper Gigabit ports with one 1G SFP slot, this switch offers flexible hybrid networking. The copper ports connect local devices (PLCs, sensors), while the SFP port supports fiber modules for long-distance, noise-immune links. This versatility bridges short-range and extended networks, perfect for sprawling facilities, remote substations, or environments prone to electromagnetic interference.
IEEE 802.1Q VLAN Transparency Support
Supporting VLAN transparency, the switch seamlessly forwards IEEE 802.1Q tagged traffic without altering VLAN IDs. This enables integration into complex networks where VLANs are managed upstream, ensuring smooth communication across segmented industrial systems like SCADA networks, smart grids, or multi-tenant infrastructure without requiring onboard VLAN configuration.
Industrial-Strength Durability
Built to withstand industrial demands, the switch features a ruggedized design resistant to shock, vibration, and electrical noise. Its hardened construction ensures reliability in challenging settings—from manufacturing plants to outdoor renewable energy sites—while maintaining plug-and-play simplicity for rapid deployment in mission-critical operations.
