01
Key Information
MTL5575 is a one-channel Eaton Crouse-Hinds series MTL5500 temperature converter for hazardous-area sensors.
It converts thermocouple, millivolt or RTD input into a nominal 4–20 mA safe-area output and provides one configurable alarm output.
Configuration through MTL PCS45 software covers linearisation, range, monitoring, testing, tagging and sensor-failure response.
02
Functions
Supports Pt, Cu and Ni RTDs in 2-, 3- or 4-wire arrangements.
Provides automatic or selectable cold-junction compensation for thermocouple service.
Allows alarm use for a process threshold or early thermocouple-failure indication.

04
Installation
Confirm the sensor type, measuring range, wiring mode and hazardous-area entity parameters before configuration.
Use the specified HAZ-CJC terminal plug for thermocouple cold-junction compensation.
Segregate hazardous- and safe-area wiring and keep connector tags matched to MTL5575.
Test the 4–20 mA output, configured alarm, sensor-break behavior and loop loading before commissioning.
05
Lifecycle
Archive the PCS45 configuration file and tag record with the MTL5575 serial identity.
Inspect connector security, screen earthing and cable condition at planned maintenance intervals.
Do not repair or modify a faulty intrinsic-safety interface in the field.
Reconfirm the sensor range and failure direction before installing a configured spare.

FAQ
Which sensor information is needed to configure MTL5575?
State the exact thermocouple or RTD type, wire count, engineering range, required output scaling and alarm behavior.
Can MTL5575 accept both RTD and thermocouple inputs?
Yes, but one installed channel is configured for one defined sensor and range at a time.
What configuration evidence should travel with an MTL5575 spare?
Keep the PCS45 file, tag, input range, linearisation, alarm setpoint and sensor-failure direction with the spare.
Why is the terminal plug important for an MTL5575 thermocouple loop?
The approved HAZ-CJC plug provides the cold-junction sensing needed for the published thermocouple performance.
What should be tested after replacing MTL5575?
Inject representative input values, verify the 4–20 mA scaling, alarm operation, open-sensor response and safe-area load.
