Process-Area Field Cabinet Edge Access
Wide-temp EMC industrial switches in process-area cabinets for instruments, serial servers, and cameras.
1. Scenario
Refining/chemical field cabinets sit near process gear—high temp and EMC demand industrial-grade access.
2. Challenges
Ex zoning and cabling codes; tight cabinets; outages hurt patrol/monitoring.
3. Architecture
2FE1FX-I in field cabinets; 8GE managed aggregation at area edge cabinets.
4. Recommended Leagrid LGS2000 products
- LGS2000-2FE1FX-I: Unmanaged DIN-rail industrial switch: 2×FE copper + 1×FE fiber, IP40, −40–85°C, EMC Level 4—edge access with fiber uplink in cabinets.
- LGS2000-8GE2GF-M: Managed Gigabit industrial switch: 8×GE copper + 2×GE SFP; VLAN/QoS/ring redundancy for intersection and shop-floor aggregation.
5. Deployment notes
Match Ex zones; bond/shield per petrochemical code; keep fiber off hot surfaces.
