MTL4544 Galvanic Isolator

The MTL4544 is a single-channel 4-20 mA galvanic isolator with full HART transparency. It provides 3-way isolation (input, output, power) for critical process signals where high accuracy and superior surge immunity are required.

The MTL4544 is SIL 2 capable per IEC 61508 and is the workhorse isolator for critical control valve and transmitter loops in refineries, offshore platforms, and chemical plants.
