Digital Filtering. The illustration above demonstrates the effect of digital
filtering (set with Filter Constant) on module response to
a temperature change.
It is recommended that the filter constant for the HE-XE102-14 be set to a
value of 7. This will minimize noise and jitter, improve effective resolution,
and provide adequate speed for most temperature monitor and control
applications.
7.2 Thermistor Linearization
Thermistors are measured using a half-bridge circuit that exhibits variable
resolution and the associated increased measurement range.
Temperature, degrees C Resolution, degrees C
-55 1.05
-35 0.36
-15 0.17
5 0.11
25 0.1
45 0.13
65 0.22
85 0.30
105 0.55
125 0.85
145 1.35
Best resolution is at 25°C, 77°F. With a constant 0 .1°C resolution circuit,
the measurement range would only extend from –26°C to +76°C.
Linearization must be performed by the user in the ladder application code,
using 26 internal %R registers per channel. The example below uses %R126 to linearize one channel - %AI1. Linearization consists of the following
example steps.
1) Load the desired linearization coefficients into a table on First
Scan using a Move Constant Data block.
5) Perform the Real Math Expression %R5 =
(((%R3*%R1+%R19)*%R1+%R21)*%R1+%R23)*%R1+%R25
6) Load %R0005 result into another register such as %R0007 to
save the temperature value.
7) Steps 2 though 5 can be on a single rung.
7.3 Thermistor types
The HE-XE102-14 with the given example ladder code supports Kele Engineering Precon Type III, 10
KΩ thermistors. It also directly supports the following 10 KΩ (Beta=3574) thermistors from Yellow
Springs Instruments (YSI).

WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of fire
and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of this
equipment and the hazards involved should install, adjust, operate, or service this equipment.
Read and understand this manual and other applicable manuals in their entirety before
proceeding. Failure to observe this precaution could result in severe bodily injury or loss of life.
