USS-6 Series 2 is a matching and conditioning unit used in the IV-500E vibration monitoring system installed on Mi-8/Mi-17 family helicopters, including upgraded models such as Mi-8MT, Mi-8AMT, Mi-171 and Mi-171E.
Its primary function is to interface piezoelectric vibration sensors with the electronic processing block (BE-9E), ensuring signal compatibility and maintaining correct input levels for accurate vibration monitoring.

The device performs electrical matching, filtering and stabilization of the vibration signals transmitted from MV-03-1 engine-mounted sensors.
USS-6 ensures reliable signal transmission from harsh engine environments to avionics equipment mounted inside the aircraft cabin.

The unit is designed for continuous operation in flight, resistant to vibration, temperature variation and electrical noise typical of airborne systems.

Alternate designations:
USS-6 may appear as USS6, УсС-6, УСС6, USS-6-2, 6Л2.***
All refer to the same component.
