4.2.4
High Side Current Monitor
The GEA 71 offers high side current monitor capability (HSCM) in 4 analog inputs. This allows aircraft
bus power to be monitored. HSCM can be enabled or disabled via unit configuration settings (see
Section 3.6).
4.2.5
Discrete Signals
Discrete In signals are active low by design. However, software configuration allows the active low state
to be interpreted as active high or active low. Discrete data is updated two times per second (2 Hz) and
outputs discrete data in RS-485 serial format to the GIA 63(W).
INACTIVE: 10 ≤ V in ≤ 3 3VDC or Rin ≥ 100kΩ
ACTIVE: Vin ≤ 1.9VDC with ≥ 7 5 uA sink current, or Rin ≤ 375Ω
Sink current is internally limited to 200 uA max for a grounded input
4.2.6
Digital In Signals
Digital input minimum frequency is 1 Hz and maximum frequency is 100 kHz. Digital signals are
updated 10 times per second (10 Hz). Maximum output high/low and low/high transition period is 5.0
µS. Digital inputs can also be configured as discrete inputs.
INACTIVE: 10 ≤ V in ≤ 3 3VDC or Rin ≥ 100kΩ
ACTIVE: Vin ≤ 1.9VDC with ≥ 7 5 uA sink current, or Rin ≤ 375Ω
Sink current is internally limited to 200 uA max for a grounded input
4.2.7
GEA System ID Program
The GEA SYSTEM ID PROGRAM 1 (P701, Pin 9) and GEA SYSTEM ID PROGRAM 2 (P701, Pin 10)
should be left open.
4.2.8
Remote Power Off
The GEA 71 powers down upon receiving the remote power-off signal. Power-off occurs when the input
is active. Remote power-off input is connector P701, pin 77.
INACTIVE: Vin <= 1Vdc
ACTIVE: Vin >= 10.0 Vdc
