Input type (temperature converter)

The signal input to the temperature converter can be set for thermocouple (THC), millivolts (mV), resistance temperature devices (RTD), or resistance (ohms).

With THC selected and linearization ‹on› temperature process units can be selected.  With THC selected and linearization ‹off›, the process units are set to ‹mV›.

If input type ‹mV› is selected then the process units are set to ‹mV› and linearization turned off automatically.

When an RTD is selected the linearization is automatically enabled and temperature process units can be selected.  When resistance input is selected the linearization is turned off and the process units are automatically set to ohms.

Note that the range of input types that can be configured varies between the different MTL temperature converters.  Refer to the product data sheets for information.

In addition to the standard input types the MTLx576-RTD and MTLx576-THC has the facility to accept user sensors that are defined to customer requirements.

The MTLx576-RTD and MTLx576-THC can be configured for dual channel (2 inputs – 2 outputs) or single channel with duplicated outputs (1 input – 2 outputs).  This latter mode enables one measured value to be provided to both a control system and a safety system through separate current loops for example.
