Product overview
MTL4573 isolated barrier 1channel Temperature converter, RTD / THC
MTL4573 isolated barrier 1channel Temperature converter, RTD / THC
MTL4573 product specification as below for your reference.
MTL4573 isolated barrier 1channel Temperature converter, RTD / THC
MTL4573 –
MTL5573 TEMPERATURE CONVERTER THC or RTD input
The MTLx573
converts a low-level dc signal from a temperature sensor mounted in a hazardous
area into a 4/20mA current for driving a safearea load. Software selectable
features include linearisation, ranging, monitoring, testing and tagging for
all thermocouple types and 2-, 3- or 4-wire RTDs. (For thermocouple
applications the HAZ-CJC plug on terminals 1–3 includes an integral CJC
sensor). Configuration is carried out using a personal computer.
