Analog Inputs (AIN)

AIN connector has four 5V analog inputs. One of the inputs is designed for the connection of a common lambda probe or a wideband lambda controller. The other inputs are for general use and allows the input of any signal from 0 to 5 volts, for example a MAP pressure sensor.

Applications

Sensors that have an output range compatible with the analog input can be connected to the auxiliary inputs, that is, around 0 to 5 volts.

The following explains how to connect pressure sensors and temperature sensors.
