- 1 Ignition input:
Ignition Input Example application:
-
IGN connected to Main switch and CH_IN12 connected to Hazard switch. With IGN active (+12V) all
functions on PDM are enabled. With IGN off (disconnected or tied to GND) and Hazard switch
active (+12V) PDM enables only outs related to HAZARD function (typically front and rear directions
lamps in hazard blinking mode).
Typically, analog sensors are pressure sensors, potentiometers, etc… while digital inputs are used for
managing pushbuttons, that may eventually be used for activating the power ouputs.

Analog inputs configuration
In the following image you see two different channels configuration windows, for analog or digital
input.
Selecting “
Analog
” options to be set are:
-
Channel name
-
Function: this parameter is useful in the data analysis process
-
Sensor type
-
Measure unit
-
Sampling frequency
-
Display precision: it configures how many decimal digits will be shown on the display
It is possible to enable an internal 2kohm pull-up, as shown in the following picture:
IGNITION INPUT: this is a special input, only digital and not programmable by user. It is active
HIGH (internal pulldown hardwired) and when activated by external voltage, switch ON the PDM.
Some functionality, for example display, are IGN dependent. This means that when IGN is active,
also display is switched ON. Ignition could be used in user configuration as condition for other
signals.
