The MTL 128 is a series of intrinsically safe barriers designed to isolate electrical signals between hazardous and safe areas in industrial environments. The 28V 300Ω specification indicates the specific model within the MTL 128 series.

Key features and benefits of the MTL 128 series:

• Intrinsically safe: Ensures safe operation in hazardous areas by preventing the ignition of flammable gases or vapors.
• Isolation: Provides electrical isolation between hazardous and safe areas, protecting personnel and equipment.
• 2-wire or 3-wire configuration: Offers flexibility for different wiring setups.
• Wide range of input/output types: Supports various signal types, including analog (4-20mA, 0-10V) and digital.
• Loop-powered: Can be powered directly from the process loop, reducing the need for external power supplies.
• Compact design: Suitable for space-constrained environments.
• Robust construction: Built to withstand harsh industrial conditions.
• 28V: The maximum supply voltage for the barrier.
• 300Ω: The input impedance of the barrier.

This information is crucial for proper selection and installation of the MTL 128 barrier in your specific application.

Applications:

• Process control: Isolating signals from field devices in hazardous areas.
