Managed Industrial Ethernet Switch NEU30162G – 16-Port Gigabit L2 Switch for Harsh Environments

NEU30162G is a Layer 2 managed industrial Ethernet switch designed for reliable communication in harsh industrial and substation environments. It offers a high‑density mix of Fast and Gigabit Ethernet ports with fiber uplinks, providing flexible connectivity for PLCs, remote I/O, HMIs, cameras and gateways inside control cabinets or along production lines. With comprehensive management features, ring redundancy and easy web‑based configuration, NEU30162G is a cost‑effective member of your managed industrial ethernet switches portfolio for demanding OEM and system‑integrator projects.

Industrial‑Grade Design for Harsh Environments
The switch adopts a fanless metal housing and DIN‑rail form factor, with an extended operating temperature range from ‑40 to 75 °C to withstand cabinet hot spots, outdoor enclosures and unconditioned substations. Industrial‑grade EMC immunity, surge and ESD protection help ensure stable operation in the presence of switching noise, lightning and heavy‑duty machinery. Redundant DC power inputs with reverse‑polarity protection and relay alarm contacts improve system uptime by enabling backup power feeds and remote fault indication.

Layer 2 Management and Redundancy Features
As a managed industrial ethernet switch, NEU30162G supports advanced Layer 2 features for traffic segmentation and optimization, including IEEE 802.1Q VLANs, QoS prioritization, IGMP Snooping for multicast control and port trunking for higher uplink bandwidth. Ring redundancy protocols such as RSTP or vendor ring allow fast network recovery when a link fails, keeping critical control and SCADA traffic running with minimal interruption. Port mirroring and statistics provide clear visibility for troubleshooting, while configuration profiles make it easy to replicate settings across multiple switches in a system.

Security and Network Diagnostics
To protect industrial networks from unauthorized access, NEU30162G offers user authentication, role‑based management passwords and port security functions that can limit which devices are allowed on each port. SNMP monitoring, Syslog, event logs and relay output alarms give maintenance teams early warning for link or power failures, helping to shorten mean time to repair. An intuitive web interface, CLI or Telnet/SSH management (depending on firmware configuration) simplifies switch commissioning and long‑term network diagnostics in the field.

Typical Applications of Managed Industrial Ethernet Switches
NEU30162G is ideal for applications where unmanaged switches are no longer sufficient, such as segmented production cells, IEC 61850‑3 power utility substations, intelligent transportation systems and city‑wide video surveillance networks. In these scenarios, engineers need managed industrial ethernet switches to implement VLAN isolation, QoS for real‑time control, redundant rings and secure remote monitoring, all of which are supported by NEU30162G in a compact DIN‑rail package.
