ARINC Abn001

Discrete Input/Output Impedance of ARINC Characteristics

This Technical Application Bulletin provides guidance to avionics manufacturers and aircraft systems integrators for attaining proper operation when interfacing discrete signal outputs from one avionics set with discrete signal inputs of other avionics. Some newer avionics are configured with discrete outputs that include short circuit protection. Such equipment will fault when working into large capacitive loads. Guidelines are provided herein for attaining interoperability.
