BASIC INFO
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.
