MTL45/46/5500 product description:


The analogue input modules, MTLx541 (single channel) and MTLx544 (dual channel) are intrinsic safety isolators that interface with process measurement transmitters located in a hazardous area of a process plant. They are also designed and assessed according to IEC 61508 for use in safety instrumented systems up to SIL3, without hardware redundancy. Each module provides a fully-floating dc supply for energising conventional 2-wire or 3-wire 4-20mA process transmitters while repeating the current flowing in the field loop into another floating circuit to drive the safe area load. The MTLx544D repeats the current flowing in a single field loop into two isolated safe area loads. For ‘smart’ 2-wire transmitters using the HART protocol the units allow bi-directional communications superimposed on the 4-20mA signal current. There are no configuration switches or operator controls to be set on the modules. These modules are members of the MTL4500 and MTL5500 range of products.
