The iEFIS Extender is used mainly to add additional capabilities to an iEFIS Lite system.
It provides 8 analog/digital inputs, 5 digital outputs, OAT sensor input, 5 RS232 serial ports (for a total of 6 usable ports on the “Lite”) as well as a AOA (angle of attack) sensor
The Extender can also be used with regular iEFIS systems where it will provide additional analog/digital inputs and digital outputs.
