MTL5575 - Temperature Converter

Temperature Input module
These modules accept inputs from low-level dc sources such as thermocouples or RTDs in hazardous
areas and converts them into 4/20mA signals to drive safe area loads.
Early burnout detection (EBD)
When EBD is selected, the resistance of the thermocouple circuit is monitored and an alarm is
raised when there is an increase of more than 50m. This enables preventative maintenance to be
conducted on the field installation before the thermocouple actually breaks.
Configuration using PCS45/PCL45USB
Use PCS45 software, in conjunction with the PCL45USB serial link, to configure these modules. Instructions
are contained within the software.

MTL5575 - Temperature Converter
Single channel, THC or RTD input with alarm
The MTL5575 converts a low-level dc signal from a temperature sensor mounted in a hazardous
area into a 4/20mA current for driving a safe-area 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 - see section 6.9. A
single alarm output is provided and may be configured for process alarm or to provide notice of
early thermocouple failure.
