Measuring system The iTEMP® TC TMT128 DIN rail temperature transmitter is a two-wire transmitter with analogue output and measuring input for thermocouples. Input values Measured variable Temperature Measuring range Depending on the application, different measuring ranges can be ordered (see ’Product structure’). Input type Output Output signal Analog 4 to 20 mA Breakdown information Breakdown information to NAMUR NE 43 Breakdown information is created when the measuring information is invalid or not present anymore and gives a complete listing of all errors occuring in the measuring system.
