The MTL 5544 is a dual-channel transmitter power supply and isolation zener barrier engineered for industrial process control applications. It provides fully floating DC supplies to energise two 2-wire or 3-wire 4-20 mA or HART transmitters located in hazardous areas, while repeating the signal to safe-area loads. With a maximum safe-area voltage rating of 28 V and an input supply of 20-35 V DC, it maintains loop integrity and supports bidirectional HART communication when required.

Standout Features and Benefits of Buying the MTL Zener Isolation Barrier

  • Dual-channel design to support two transmitter loops.
  • Suitable for 2-wire or 3-wire 4-20 mA/HART transmitters.
  • Fully floating supply for hazardous-area transmitter circuits.
  • Safe-area output voltage limited to 28 V “U₀” rating.
  • Supports bidirectional HART communication superimposed on loop current.
  • Wide ambient operating range (–20 °C to +60 °C).
  • SIL-capable for functional safety applications (single device SIL 2, redundant configuration SIL 3).

Designed for Safe Process-Signal Transmission

The MTL 5544 is engineered for environments where intrinsic safety and signal integrity are critical. With certified functional-safety ratings, this unit supports safety-instrumented systems (SIS) and industrial control architectures with traceability and reliability.

Product Use Cases

  • Powering and isolating 4-20 mA loops in hazardous-area zones (Zone 0/1).
  • Integrating HART-enabled 2-wire or 3-wire smart transmitters in hazardous environments.
  • Repeating or isolating signals from field transmitters to PLC/DCS safe-area inputs.
  • Supporting functional safety installations with SIL-capable loop barriers.
  • Use in process industries (oil & gas, chemical, petrochemical, utilities) where loop integrity and safety matter.
