OPERATION:
The Model A655-8-3000 timer is a microprocessor-based
device capable of performing 2 different timing modes
over five different timing ranges.The timing ranges allow
for delays from 1 millisecond to 199 hours 59 minutes.
The timing modes and ranges are selected using a DIP
switch assembly located on the inside of the timer.
The time setting is entered through the front panel key-
pad while the time value is displayed on the LCD readout.
The timer keypad can be disabled to guard against acci-
dental time changes by using the internal DIP switch.
The timer is housed in a standard 15-terminal plug-in
round case and can directly replace most existing electro-
mechanical 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
A655 timer models are available for operation on either
120VAC or 240VAC.
