The EDS-G4012 Series is a family of compact, full-Gigabit managed switches designed for industrial backbone and edge applications. With 12 Gigabit ports and options for up to 8x IEEE 802.3bt PoE ports delivering 90 W each, the series supports high-bandwidth and high-power devices such as PTZ cameras, wireless APs, and industrial controllers.
Certain models feature four SFP uplinks with speeds up to 2.5 Gbps, enabling faster backbone performance and long-distance fibre connectivity. Non-PoE variants offer 8x copper ports and 4x combo ports for cost-efficient deployments.
Certified to IEC 62443-4-1 and IEC 62443-4-2 cybersecurity standards, the switches integrate robust security features including IEEE 802.1X, RADIUS/TACACS+, SNMPv3, HTTPS, SSH, and role-based access control. Redundancy mechanisms include Turbo Ring and Turbo Chain with <50 ms recovery across 250 switches, plus standards-based RSTP/STP for multi-vendor environments.
Flexible power options cover LV (12/24/48 VDC) and HV (110/220 VDC/VAC), with both single and dual redundant feed models. Standard models operate from -10 to 60°C, while wide-temperature (-T) versions extend to -40 to 75°C.
Compact IP40 housing with DIN-rail or wall-mount options allows easy deployment in confined spaces. With a mix of PoE and non-PoE variants, high-speed uplinks, redundant power inputs, and certified cybersecurity, the EDS-G4012 Series provides a reliable platform for video surveillance, ITS, DCS, and other mission-critical industrial networks.
