Discrete Inputs
The GEA 24 has 4 configurable discrete inputs that can be used as either Active High or Active Low.
These inputs are configured by the GDU (refer to
for GDU 4XX systems).
When configured as Active Low, the inputs conform to the following specification:
Active: Vin < 3.5 VDC, or Rin < 375
Ω
Inactive: Vin > 8 VDC, or Rin > 100 k
Ω
When configured as Active High the inputs conform to the following specification:
Active: Vin > 8 VDC, or Rin > 100 k
Ω
Inactive: Vin < 3.5 VDC, or Rin < 375
Ω
The GP1-GP7 inputs may also be used as additional discrete inputs. If GP6 or GP7 are used for this
purpose, the corresponding GP6 LO or GP7 LO pin must also be connected to ground (see
