Analog Inputs

The controllers support a variety of analog inputs. The input's allowable voltage range varies
depending on the primary purpose of the input. Select the analog input that matches the application.

The measurement margin is +4% / –0% margin. This is for analog usage.
1
The full-scale accuracy is ± 2% over temperature (referenced to room temperature, 25°C).
The input signal filter is > 1 kHz for standard and pot inputs, > 40 kHz for encoder & sin/cos inputs.
When using potentiometer inputs, due to the dynamic tests (see text, below), the voltage reading is not constant. Use the input
2
percent variable for the throttle or controls value.
Increase voltage normalization range (analog_input_x_high) maximum limit to 30V for analog inputs, such that they can be used
3
as digital (switch) inputs without causing a voltage out-of-range fault.
