Terminals)
Analog Input Value or
Temperature Input Value
The following math operations can be performed on the external analog input
value or temperature input value. The values obtained after processing (ana-
log input values or temperature input values) can be allocated as I/O in the
Master.
• Scaling to desired industry unit
• Moving average processing (not supported by the DRT2-AD04H)
Other Operation Results After moving average and scaling processing, the analog input value or tem-
perature input value can be processed using the following operations. The val-
ues after processing are called peak value, bottom value, top value, valley
value, rate of change, and cumulated value.
• Peak/hold operation
• Top/valley operation
• Rate of change operation
• Cumulative operation (maintenance function)
Comparator Compares the temperature input value or an analog value
after math processing (value for peak, bottom, top, valley,
rate of change) with the four set values HH, H, L, and LL,
and indicates the result with the Analog Status Flags.
Disabled
Off-wire detection Detects disconnections of analog inputs. Enabled
User adjustment An offset caused by hardware inaccuracy (or other factor)
can be corrected with an arbitrary user-set input value.
Disabled
Last maintenance date Records the date of the last maintenance in the Unit. 2004/1/1
Input temperature variation
detection function
Makes a relative comparison of two inputs and detects a
temperature difference between two inputs.

integration func-
tion
Compiles the total heat exposure of a device or sensor by
multiplying the temperature and measurement time.
Disabled
Top/Valley count
function
Counts the number of heating cycles handled by a device
or application that has fixed cycles of temperature
changes.
Disabled
Temperature
range timing
function
Measures how long the system is at a user-set tempera-
ture or within a user-set temperature range.
