The 1734-IT2I module consists of two isolated millivolt inputs (+70 mV).
Configure the module to do the linearization necessary for thermocouple
inputs. See the table for a list of supported thermocouple input types.

The 1734-IR2 consists of two RTD inputs (0...600 W). Configure the module
to do the linearization necessary for RTD inputs. See the table for a list of
supported input types.

The 1734-IR2E consists of two RTD inputs (0...200 W). Configure the module
to do the linearization necessary for RTD inputs. See the table for a list of
supported input types.
I/O messages are sent to (consumed) and received from (produced) the
POINT I/O modules. These messages are mapped into the processor's
memory. The Thermocouple input module produces 8 bytes of input data
(scanner Rx) and fault status data. It does not consume I/O data (scanner Tx).
The RTD input module produces 6 bytes of input data (scanner Rx) and fault
status data. It does not consume I/O data (scanner Tx).
