IES7120-12T4F4GS – 20-port managed industrial switch with 12×RJ45, 4×fiber ports and 4×Gigabit SFP

The IES7120-12T4F4GS is a high-performance, fully managed industrial Layer 2 Ethernet switch designed for demanding applications in energy distribution, railway systems, industrial automation, smart cities and large-scale CCTV deployments. It provides 12× 10/100Base-T(X) copper ports, 4× 100Base-X fiber ports and 4× Gigabit SFP 1000Base-X slots, offering exceptional flexibility for building long-distance, redundant and high-bandwidth industrial networks.

As part of the IES7120 series, the device supports advanced industrial redundancy mechanisms including Ring recovery <20 ms, STP/RSTP/MSTP and ERPS (G.8032). These technologies enable the creation of deterministic and fault-tolerant communication structures essential for mission-critical control systems.

Comprehensive management capabilities include IEEE 802.1Q VLAN, QoS, IGMP Snooping, LACP, LLDP, DHCP Server, DHCP Snooping and ACL-based security. Integrated Modbus TCP monitoring allows SCADA systems to supervise device temperature, power status, link conditions and network events in real time.

The switch offers extensive diagnostic and troubleshooting tools such as Ping, Traceroute, Cable Test, Port Mirroring and SFP DDM for optical transceiver monitoring. Security features including SSH, HTTPS, RADIUS and TACACS+ ensure safe remote access and protection of configuration data.

Engineered for harsh industrial environments, the IES7120-12T4F4GS features a rugged IP40 metal enclosure, fanless heat dissipation and a wide operating temperature range of −40…75°C. Its EMC resistance meets IEC 61000-4 standards with ±15 kV ESD, ±4 kV EFT and ±4 kV surge protection, ensuring stability in electrically noisy installations.
