MTL5575 1channel Temperature converter, RTD / THC with alarm
MTL4575 –
MTL5575 TEMPERATURE CONVERTER THC or RTD input + Alarm
The MTLx575
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. A single alarm
output is provided and may be configured for process alarm or to provide notice
of early thermocouple failure.
