Operation:
The Model 651 Timer is a microprocessor-based
device capable of performing four different timing modes over three
different timing ranges. The timing ranges allow for delays from,100
milliseconds to 99 hours 59 minutes. The timing modes and ranges
are selected using s DIP assembly located on the inside of the timer.
The time setting is entered through the front panel keypad while
the time value is displayed on the LCD readout. The timer keypad
can be disabled to guard against accidental time changes. The timer
is housed in a standard 12-terminal plug-in round case and can directly
replace most existing electromechanical or electronic plug-in round
case timers. A totally sealed faceplate allows this timer to be
used in harsh environments. Both instantaneous and timed contacts
are provided and Mode1651 timers are available for operation on
either 120 Vac or 240 Vac.
