Astrotech AT420000 Model LC-2 Black Aircraft Powered 14/28-Volt Lighting 2-1/4" Panel Hole Mounted Clock-Timer

The Astrotech model LC-2 chronometer uses a custom designed microprocessor circuit which controls all clock/timer functions. The microprocessor is attached to a single circuit board, a simplified construction technique resulting in a high degree of reliability and performance at a low cost. Circuitry is not subject to dirt, vibration, friction, or the wear characteristics of mechanical clock movements.
