Product Overview
MTL4544 is a dual-channel intrinsically safe isolator for 2-wire or 3-wire 4–20 mA/HART transmitters located in hazardous areas. It provides transmitter power and repeats the 4–20 mA signal to the safe area while maintaining full HART transparency.
Key Specs
- Channels: 2 independent
- Signal: 0–24 mA (4–20 mA nominal) with HART
- Transmitter supply: 16.5 V at 20 mA per channel
- Safe-area load: Up to 450 Ω @ 20 mA class
- Accuracy: ±15 µA at 20 °C class
- Power dissipation: Approx. 1.4 W @ 24 V DC
- Mounting: MTL4500 backplane
Why Choose This
- Dual independent HART-compatible channels
- Powers and isolates hazardous-area transmitters
- Fast response for process control
- Certified for Zone 0 / Div 1 applications
Common Questions
