2.6.3 Universal Sensor
Universal Sensors have the ability to be configured to detect different sender types (0-750
Ω, 0-7,500 Ω,
0-5 VDC, 4-20 mA). The examples shown below are advanced applications of the universal sensor.
CAUTION
CUSTOM SENDER TABLES ARE REQUIRED FOR THE UNIVERSAL SENDER TO WORK WITH
THESE EXAMPLES. SEE THE
CUSTOM SENDER TABLES SECTION FOR MORE INFORMATION.
ATTENTION
LES TABLEAUX CUSTOM SENDER (EMETTEUR PERSONNALISE) SONT NECESSAIRES POUR
QUE L'EMETTEUR UNIVERSEL FONCTIONNE AVEC CES EXEMPLES. VOIR LA SECTION

Example #1 : The following example shows the correct way to wire a 4-20 mA sensor. The 240
Ω resistor is
required to transform the 4-20 mA current into the 0-5 V voltage range required by the controller.
4-20 mA Wiring Example
Example #2 : Sometimes it is required to measure voltages outside the 0-5 V range allowed by the controller. To
do this you must use a voltage divider with appropriate scaling resistors. The equation to calculate the resistor
values is as follows:
V
OUT
= (R1/(R1+R2)) × V
IN
Where: V
OUT
= 5 V
V
IN
= Maximum Voltage to Read
R1 = Common Resistor Value > 10
kΩ
R2 = Calculated Resistor Value (select closest common
resistor value)
The following diagram shows the typical wiring of a voltage divider. The resistors
’ values have been selected to
allow the controller to read up to 36 V from an external battery bank.
