The L2C and L4C are dedicated large display clocks,
which can be configured for real-time or elapsed time indication.
Four-digit or 6-digit units are available offering displays
indicating minutes/seconds or hours/minutes (4-digit) and
hours/minutes/seconds or days/hours/minutes (6-digit).
Remote controls and preset capability along with an alarm
output make the run time clock an ideal process timer. An
RS-232-C output of the display is provided to permit connection
of a number of slave clock displays to a master clock with
only 3 wires.
