TIMER (P/N 25-nf1565) - As Removed

The 25-nf1565 is an aircraft timer that controls electrical sequencing and introduces protective time delays in flight systems. This hermetic relay device manages on-delay timing for equipment warm-up cycles and circuit protection sequences. Installed in aircraft control circuits per wiring diagrams and maintenance manuals, it provides reliable delay functions in avionics, engine management, and environmental control systems.

Qualified maintenance personnel should verify installation against aircraft-specific documentation and perform functional testing to confirm delay accuracy and electrical continuity.
