MCI Chronos Digital Clock 6420093-0

The CH93 series is a multi-function digital clock / chronometer / voltmeter / temperature unit. The unit fits into a standard, rear-mounted, 2-¼ avionics panel cutout. Power is drawn from the aircraft main bus to light a white, six digit, seven segment LED clock. The clock can display several different modes: local time, universal time, flight timers, elapsed and countdown timers and optionally, bus voltage and up to two temperature inputs. The CH93 display is daylight readable with two methods of brightness control. It can be controlled automatically using the internal photocell or manually with an external dimming bus voltage. The CH93 clock has an internal battery to maintain clock time and flight timer memory when the aircraft is not in use.
