The EDS-305-M-ST combines four copper RJ45 ports with one ST multi-mode fibre port, enabling integration of legacy ST fibre with modern copper devices. Supporting fibre runs up to 4 km, it’s well-suited for industrial networks where ST connectors remain in use.
The switch includes a relay output that warns of power loss or port-break events, helping operators respond rapidly to faults. Broadcast storm protection is available through DIP switch configuration for improved stability during heavy traffic.
Built in an IP30-rated metal housing, the unit is certified for hazardous areas (Class I Div. 2, ATEX Zone 2), maritime (DNV-GL), and EMC/safety standards. Compact DIN-rail mounting allows easy installation in control panels and field enclosures.
Redundant dual 12/24/48 VDC power inputs, with overload and reverse polarity protection, enhance uptime resilience. Each model undergoes 100% burn-in testing and is tested for shock, vibration, and EMC immunity.
Operating in the Standard 0°C to +60°C range, the EDS-305-M-ST offers long-term, dependable unmanaged switching for process automation, factory networks, and monitoring systems using ST fibre.
