IES7120-16T4GS-HV – 20-port managed industrial switch with 4×Gigabit SFP and 110/220VAC/DC power input

The IES7120-16T4GS-HV is a fully managed industrial Layer 2 Ethernet switch designed for mission-critical communication networks. It offers 16× 10/100Base-T(X) copper ports and 4× 100/1000Base-X Gigabit SFP slots, enabling high-bandwidth fiber uplinks and flexible network design. As part of the IES7120 series, it is engineered for applications that require high reliability, deterministic communication and strong EMC immunity such as smart-grid systems, railway networks, industrial automation, smart city infrastructure and large CCTV deployments.

This HV (High Voltage) variant supports a wide-range 110/220VAC/DC power input, making it suitable for installations where industrial AC or DC power sources are standard. A built-in alarm relay and comprehensive LED indicators provide real-time information on power status, link activity and port faults, enhancing operational visibility and maintenance efficiency.

The switch supports a complete set of industrial redundancy protocols including STP, RSTP, MSTP and ERPS (G.8032). Combined with the integrated Ring recovery mechanism offering switching times below 20 ms, the IES7120-16T4GS-HV ensures continuous, interruption-free operation even in the event of link or node failure.

Advanced Layer 2 management functions include IEEE 802.1Q VLAN, QoS prioritization, IGMP Snooping, LLDP, LACP, DHCP Server, DHCP Snooping, ACL filtering, 802.1X authentication and more. The switch also supports Modbus TCP monitoring, allowing integration with SCADA systems and real-time supervision of port status, temperature, voltage and system events.

Diagnostics and troubleshooting are supported through tools such as Ping, Traceroute, Cable Test, port mirroring and SFP DDM for fiber monitoring. Security is reinforced with SSH, HTTPS, RADIUS, TACACS+, user-level access control and encrypted communication channels.

The IES7120-16T4GS-HV is built for harsh operating environments. Its rugged IP40 metal enclosure, fanless design and wide temperature range −40…75°C ensure long-term performance in field cabinets, substations and industrial plants. High EMC immunity, including ±15 kV ESD, ±4 kV EFT and ±4 kV surge protection, guarantees reliable operation in electrically noisy environments.
