7.1 Equipment Description
The GEA 24 is an input/output system used to monitor and power engine and airframe sensors for the
Experimental – Amateur Built (E-AB) and Light Sport Aircraft (LSA) markets. In a G3X™ avionics or
G3X Touch™ avionics system, two GEA 24 units may be installed to monitor and display engine data for
twin-engine aircraft, or single-engine aircraft with more than six cylinders. The second GEA 24 must be
configured as EIS #2 as described in Section 23.4.16
.
• 9 pin network-power connector
• 50 pin miscellaneous connector for airframe sensors
• 25 pin thermocouple input connector
• 37 pin miscellaneous connector (for airframe sensors) will provide for the following input/output
functionality:
◦ Configure analog, digital, and discrete I/O capability
◦ Output digital measurement of analog input resistive sensors
◦ Output digital measurement of analog input voltages
◦ Output digital state of discrete input sources
◦ Output frequency measurement of digital input sources
◦ Control of discrete annunciator outputs
NOTE
If a GEA 24 is installed in a system that also includes a GSU 73, the GEA 24 must be
configured as EIS #2 as described in Section 23.4.16
