Eaton MTL5500 DIN-rail IS isolators
MTL5500 DIN-rail intrinsic safety isolators: slim single and multi-channel modules, 3-port isolation and removable connectors – from single loops to full cabinets.
- Slim DIN-rail modules, single and multi-channel
- 3-port isolation with low power dissipation
- Removable connectors for fast installation and maintenance
- Broken-line monitoring, HART compatible
- Many SIL-assessed models
- Pluggable replacement for preceding MTL isolators
Overview
The MTL5500 range of intrinsic safety isolators meets the needs of application-focused projects, from single instrument loops to fully equipped cabinets, protecting signals entering hazardous areas.
Slim housings suit many space requirements, and single and multi-channel modules let users choose functionality without sacrificing cabinet space. All signal wiring uses removable connectors.
VTL reference projects: Thi Vai LNG terminal, Ninh Binh fertiliser plant.
