The GEA 71 offers high side current monitor capability (HSCM) in 4 analog inputs. This allows aircraft
bus power to be monitored.

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 63W. Discrete inputs are low when the signal is
≤ 1.9 VDC or the resistance to ground is ≤ 375 Ω , and are otherwise high.
