MTL5000 Range

Brand: MTL Instruments
Add Product to My Catalog

MTL5000 range of isolators provide intrinsically safe (IS) communication and signal conditioning for a wide range of hazardous-area devices. Total ac and dc isolation exists between input, output and power supply on separately powered units, and between input and output on loop-powered units.

No IS earth is required. DIN-rail mounting and plug-in signal and power connectors simplify installation and maintenance. Units are powered from a 20 to 35V dc supply, or, in some cases, from the signal itself.
