MTL5500 DIN Rail Mounted Intrinsically Safe Isolator

The MTL5500 range of intrinsic safety isolators are designed to meet the needs of the IS interface market for application-focused projects, from single instrument loops to fully equipped cabinets. Protecting electrical signals in potentially flammable or other hazardous areas. Helping to ensure a safe work environment and protect those nearby from explosion risks.

MTL5500 electrical isolator range has a slim, compact housing to suit a variety of space requirements and the range of module options contains both single and multiple channel devices which enable the user to choose the functionality and integrity needed without sacrificing cabinet space. The modules can be used for a wide variety of interface tasks for process instrumentation.

All signal wiring is made through removable connectors which facilitate fast installation and simple maintenance procedures.
