Product Description
MTL5582B Resistance Isolator Overview
The MTL5582B resistance isolator connects to 2-, 3-, or 4-wire resistance temperature devices (RTDs) located in hazardous areas, providing isolation and resistance transmission to monitoring systems in safe areas. This non-configurable module serves as an alternative to the MTLx575 for applications requiring resistance input instead of 4-20mA signals.
Key Features
• Supports 2-, 3-, or 4-wire RTD connections (user-selectable via switches)
• Designed primarily for Pt100 3-wire RTDs
• Independent wiring configuration between hazardous and safe areas
• Open-circuit detection with upscale drive to 420Ω
• Excellent repeatability and ease of use
• Factory-set for 3-wire operation
