“Temperature sensor 1 wire” in the application “Sensor Settings”. ELT input is internally

pulled up by 2.2kΩ.

Analog input 0 –3 or 0 –10 Voltage

Input signal between input and ground.

Select “Analog input 0-3V” or ”Analog input 0 – 10V” in the application “Sensor

Settings”. ELT input is internally pulled down.

/ 0-10V

Powered analog input 0 –10V

Input signal between input and ground. +3V present at B+ pin.

Select “Analog input” in the application “Sensor Settings”. Select “Eternal startup time”

and configure ON-time for sensor. External startup time is how long the sensor will be

powered before sampling value. ELT input is internally pulled down and the input

impedance is 7.4 kΩ

Pulse count (Pull up)

Input signal between input and ground.

Select “Pulse input (pull up)” in the application “Sensor Settings”. ELT input is internally

pulled up by ~50 k Ω*.

Pulse count (Pull down)

Input signal between input and B+.

Select “External startup time” in the application “Sensor Settings” and configure ON-time

for always on that is >1000000ms.

Select “Pulse input(pull down)”. ELT input is internally pulled down by ~50 kΩ*.

Pulse count (Pull down) –External pulse

Input signal between input and GND. Pulse signal from 3 to 12 voltage.

Select “Pulse input (pull down)” in the application “Sensor Settings”. ELT input is

internally pulled down by ~50 kΩ*.
