The MTL5500 series intrinsically safe isolators are DIN rail mounted, high efficiency isolating interfaces with system vendors in mind. The MTL5500 series is the latest generation of IS interfaces which utilize an innovative "One-Core" technology to ensure the highest quality and availability while maintaining maximum flexibility at lowest cost. Incorporating advanced circuit design, a common set of components and innovative isolating transformer construction, they achieve a significant reduction in power consumption while increasing channel packing densities.

The DIN-rail mounting MTL5500 Series meets the needs of the IS interface market for "application focused" projects, ranging from single instrument loops, through to fully equipped cabinets, across all industries where hazardous areas exist.

The MTL5500 clips quickly onto DIN rail, so it is compatible with the industry-standard mounting system. Wiring is simplified by plugin safe- and hazardous-area connectors, and a power plug which accepts a power bus; it all leads to quicker insertion, fewer wiring errors and trouble-free, tidier installations.

Status LEDs, configuration switches and ports are located on the top or side of individual MTL5500 modules, as appropriate, for easy access. In addition to their use in IS circuits, specific MTL5500 models have been assessed and approved for use in Functional Safety applications. These have been verified under the certified Functional Safety Management (FSM) program implemented by MT
