Eaton MTL4500 backplane-mounted IS isolators
Backplane-mounted intrinsic safety isolators for DCS, ESD and F&G – highest channel density, 3-port isolation, low power, many SIL-assessed models.
- Backplane mounting for direct DCS/ESD/F&G integration
- Highest module/channel packing density, single and multi-channel
- 3-port isolation, low dissipation, planar transformer technology
- Quick install-and-release, broken-line monitoring
- Many models assessed for functional safety (SIL)
- Replaces preceding MTL isolator ranges
Overview
The MTL4500 range of backplane-mounted intrinsic safety isolators protects electrical signals entering potentially flammable hazardous areas, helping keep people and plant safe.
Built around planar transformer technology and highly automated manufacture, MTL4500 is designed for system vendors and project applications such as DCS, ESD and F&G: fast module installation, easy integration, low-power circuits and more I/O channels per module.
