Detailed Product Description


The MTL5544D provides a fully-floating dc supply for energizing a conventional 2- or 3-wire 4/20mA transmitter located in a hazardous area, and repeats the current in other circuits to drive two safe-area loads. For HART 2-wire transmitters, the unit allows bi-directional transmission of digital communication signals superimposed on the 4/20mA loop current. Separately powered current sources, such as 4-wire transmitters, can be connected but will not support HART communication.

MTL5500 Series Barriers                                                                                                                      

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

These contrasting attributes stem from the progression of MTL's 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.

Compact modular design with DIN rail mounting

High packing density

Single and multi-channel I/O modules

3-port isolation with low power dissipation

Compatible with MTL5000
