25.5.18 Transducer Output Power
The GEA 24 supplies output power for engine/airframe sensors that may require supply voltage excitation.
The GEA 24 outputs voltage levels of +5 and +12 Vdc. Each output can supply a maximum of 50 mA. If
more than 50 mA is needed for a sensor, 3 outputs of the same voltage may be spliced together to allow an
output current of up to 100 mA. Transducers that require more current (such as Princeton capacitive fuel
quantity converters) must be supplied from aircraft power instead of GEA 24 transducer power output
pins.
The transducer output pins are listed in the following table. Additionally, the pins are also listed in the
tables for their respective default functionality.
