25.5.12 GP (General Purpose) Inputs
These inputs are configured by the GDU (refer to
for GDU 4XX systems) and are capable of reading any voltage up to 40 Vdc. The GEA 24 has 7
position inputs, labeled POS 1 through 7, and 7 general purpose inputs, GP 1 through 7 (to limit the length
of pin names, “GPX” is not used on all pins), each of these are paired together.
When using the GP6 and GP7 inputs for general-purpose voltage sensing, including position sensors and
user-defined analog parameters, the corresponding GP6 LO or GP7 LO pin must be connected to ground.
The GP1-GP7 inputs may also be used as additional discrete inputs. When configured as an Active Low
discrete input, the GP1-GP7 inputs require an additional pull-up resistor, as shown in
.
Potentiometer based sensors can be used by connecting the potentiometer across a +5 V supply and ground
and reading back the center tap voltage on GP1-G7/POS1-7. Some General Purpose inputs have multiple
functions.
