MTL Intrinsic Safety barrier

MTL is mainly engaged in the production and R & D of products used in flammable and explosive hazardous areas, and occupies a leading position in the world in this field. Our products range from well-known Zener type safety barriers and barriers in the industry to advanced process control products. All products are suitable for the harsh environment in the process industry area.

Intrinsically Safe Isolators

We offer the best choice in DIN-rail and backplane mounting isolators to meet the requirements of modern systems. The DIN-rail mounting isolator ranges provide a wide choice of functions with high accuracy and reliability, while the backplane mounting products are established as the leading IS system interface with solutions for all the major DCS companies.

The MTL4500 range is the latest generation of backplane mounting products, building upon the heritage of MTL4000 and introducing many key application benefits.

The MTL5500 range launches a new industry standard for DIN rail mounting products, ideally suited to a wide variety of interface tasks for process instrumentation.
