Industrial Applications

1. Industrial Control Room Network Aggregation

Integrates multiple programmable logic controllers (PLCs), human-machine interfaces (HMIs), and industrial PCs in a control room environment.

Problem Solved

Industrial facilities often contain airborne dust which can lead to active fan failure and system breakdown. The fanless, passive design of the TL-SG2218 eliminates fan failure risks entirely, ensuring consistent local gigabit networking without drawing in dust.

2. Factory-Floor to Main-Server Fiber Uplink

Connecting remote manufacturing sections or assembly areas to a central control cabinet located several kilometers away.

Problem Solved

Standard copper cables are limited to 100 meters and are highly susceptible to electromagnetic interference (EMI) from heavy industrial machinery. Utilizing the 2 Gigabit SFP slots, engineers can run noise-immune fiber-optic cables directly to the facility's backbone.

3. Industrial Security and Access Control Subnetwork

Isolating and managing surveillance feeds, badge readers, and door strikes across an industrial campus.

Problem Solved

Mixing security traffic with general operational data risks cyber-vulnerabilities or packet loss. Advanced 802.1Q VLAN support and robust Access Control Lists (ACLs) allow complete physical-logical segmentation of the facility's security hardware.
