Analog Inputs / 5 Volt Excitation. 11-1
11.1 Analog Inputs Overview
The four generic analog input channels are configured as single ended inputs with a default range
of 0.0 to 5.0 volts. A 5.00 volt switched excitation is also provided for sensors that require a
precision power reference. The analog setup screens allow the user to make simple conversions
from voltage to the desired units by defining a slope and offset for the analog input. The voltage
from the input is multiplied by the slope value and added to the offset value to produce the final
value.
11.2 Analog Menus
Built in Menu Structure: Analog Input Options.
