7.2.5 RTD Input Block Description (RTI)
This block is used to input a RTD value and translate it to a scaled temperature. It receives its
input from a RIM or WRIM module block only. A functional block diagram of a RTD input
block is shown in Figure 7-13. Menus used to configure the block re shown in Figure 7-14
and Figure 7-15.
The mnemonics, valid values, and data types for all fields that may be
selected for display and/or be used in making softwiring connections are listed in Table 7-5.
Section 7.2.8 further defines the input block configuration parameters.
