The MTL4850 HART Multiplexer offers a smaller footprint solution ideally suited to both retrofit and new project applications. Termination boards, carriers, and integrated backplanes are available to enable the MTL4850 to interface to various instrumentation applications.

The MTL4850 Multiplexer offers the following benefits:

  • Channel to channel isolation
  • Isolated power supply
  • Auto baud-rate detection
  • LED indication for fault diagnosis
  • Supports HART Rev. 5-7 devices
  • SIL3 certified for connection to safety loop
  • Onboard event log
  • ATEX, FM and CSA certification

The MTL4850 Hart Multiplexer is now Safety Integrity Level (SIL) 3 rated for connection to instrument loops performing safety functions up to and including SIL3. The international standard IEC 61508:2010 provides guidelines to achieving an adequate SIL for systems, sub-systems, and components. Functional Safety Management requirements are found in IEC61508, which states that suppliers and subcontractors shall demonstrate functional safety management.

MTL conforms to the requirements of the international standard IEC 61508:2010 for functional safety by being certified as a Functional Safety Management company.
