MTL4576-RTD product specification as below

MTL4576-RTD safe barrier 2 channel Temperature converter, RTD

MTL4576-RTD – MTL5576-RTD TEMPERATURE CONVERTER RTD/potentiometer input, 2-channel The MTLx576–RTD converts signals from resistance temperature detectors (RTDs) mounted in a hazardous area, into 4/20mA currents for driving safe-area loads. Software selectable features include input type and characterisation, ranging, monitoring, testing and tagging. Configuration is carried out using a personal computer. The MTLx576– RTD is compatible with 2– and 3–wire RTD inputs. The MTLx576-RTD can also be configured to drive two safe-area loads from a single input.
