Products: A440Y-23 / A440Y-33 Test Adapters
The A440Y-23 and A440Y-33 adapters interface with the Collins 980L-1/-1A test panel and contain the necessary loads and special circuitry to test and troubleshoot Collins Attitude and Flight Director Indicators as per the manufacturer's test procedures.
Equipment Description
These newly designed adapters incorporate current PC Board Technology which will ensure increased reliability and reduce maintenance.
The adapters have 16 plugs mounted on the rear connector bracket which mate with the connectors on the 980L-1/-1A.
The A440Y-23 has cables extending from a single outlet on the front panel of the adapter.
The A440Y-33 has two cables extending from two outlets on the front.
The 980L-1/-1A generates AC and DC signals similar to those applied in flight to the unit under test. These signals are applied to the adapter. The adapter directs these signals to the unit under test or back to the 980L-XX switches in the switching matrix. The matrix switches in the 980L-XX are divided into three principal groups: Input, Output, and Test Set functions.
