Inputs
The PDM32 has the following input channels:
•
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).
•
8 channels (CH_IN1 - CH_IN8)
: can be both analog and digital in dependence upon the configuration
(please, refer to the paragraph “Input channels configuration).
If they are configured as analog, a 2KOhm pull-up can be activated.
If they are configured as digital, it is possible to activate an internal pull-up or pull-down depending on
whether they are closed to ground or closed to VBatt.
•
4 channels (CH_IN9 - CH_IN12)
: they are only digital and can have a pull-up or a pull-down depending
on whether they are connected to ground or to VBatt.
•
2 speed inputs
The input channels CH_IN11 and CH_IN12, when connected to VBatt, can activate the
PDM without turning on the display. This can be useful for activating the Hazard, or
keeping a fan on even with the engine off until the temperature reaches a correct value
etc.
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.
