Overview
Designed for Demanding Industrial Operations: Reliable Network Power & Control
Features
Industrial-Grade Reliability & Extended Temperature Tolerance
Engineered for harsh environments, this 4 port web managed industrial PoE switch delivers uninterrupted operation across -40°C to 75°C with IP40-rated housing, 8KV surge protection, and DIN-rail mount durability. Deploy confidently in extreme settings: sub-zero cold rooms, high-heat manufacturing cells, or particulate-heavy facilities. Resist voltage fluctuations from heavy machinery and electrical storms. The space-efficient design optimizes control panel or enclosure layouts.
Scalable Fiber-Optic Uplink Connectivity
Dual hot-swappable SFP slots enable flexible fiber-optic backbone links (single/multimode) or copper extensions. Overcome 100-meter Ethernet limitations – span distances up to 120km. Seamlessly integrate remote IP surveillance systems, sensors, or daisy-chained switches. Eliminate electromagnetic interference (EMI) in electrically noisy industrial plants via optical isolation.
Intelligent PoE++ Provisioning & Control
Configure and automate 4 × IEEE 802.3at PoE+ ports (30W/port, 120W total) via intuitive **web management**. Schedule power cycling for efficiency, remotely reboot connected devices, and establish PoE priority tiers during outages. Deliver data and power over single cables to IP cameras, wireless access points, and access control systems – eliminating local power sources.
Enterprise-Grade Traffic Segmentation & Security
Implement VLAN segmentation, QoS traffic shaping, bandwidth throttling, and storm control protocols. Isolate OT systems (PLCs/SCADA) from IT networks. Guarantee bandwidth for mission-critical video surveillance feeds and VoIP. Suppress broadcast storms that destabilize operations.
Centralized Cloud-Style Web Management
Administrate your entire deployment via an intuitive browser-based interface. Configure VLANs and ring network topologies in minutes without CLI skills. Monitor real-time port status, power loads, and traffic analytics. Receive automated alerts for faults or intrusions.
