MTL5500 Range Intrinsically Safe Isolators

Brand: MTL Instruments

he MTL5500 range modules are versatile yet simple to apply; use the latest technology and yet are well proven.

These contrasting attributes stem from the progression of our expertise in the design and manufacture of isolators for intrinsic safety and the application of innovative technology to achieve the required separation and segregation of the circuits.

The MTL5500: DIN-rail mounting and MTL4500: backplane mounting isolators share a common design, differing only in the mechanical mounting and connection methods.
