WHAT IS A TIME DELAY RELAY:
A Time Delay relay is a combination of an
electromechanical output relay and a control circuit.
The control circuit is comprised of solid state
components and timing circuits that control operation
of the relay and timing range. Typical time delay
functions include On-Delay, Off-Delay, Repeat cycle,
One Shot, Interval, On-Delay & Off Delay (Combination)
and True Off Delay. Each function is explained below.
Time delay relays have a broad choice of timing ranges
from less than one second to hours. There is a choice
of timing adjustments from calibrated external knob,
recessed pots or internally fixed timing. The output
contacts on the electromechanical output relay are
direct wired to the output terminals. The contact
load ratings are specified for each specific type of
time delay relay.
TIMING FUNCTIONS:
ON-DELAY- (SLOW OPERATE RELAY)
Upon application of power to the input, the time delay
period begins. At the end of the time delay period,
output contacts transfer. Input power must be removed
to return output contacts to home position and reset
the control circuit. If input power is interrupted before
a timing period ends, timing stops. When input power
is restored , timing starts from the beginning.

OFF-DELAY (SLOW RELEASE RELAY)
Continuous power must be applied to input during all
timing sequences. Upon closure of external control switch,
the timing period begins. When timing period ends, output
contacts return home. To repeat this timing cycle, the
control switch must be re-closed and then opened. If input
contacts return to home position and the control switch
must be closed and reopened to start the timing from the
beginning. If the control switch closes during a timing
period, timing stops and output contacts remain
transferred. When control switch is opened, timing will
start again from the beginning. The timing period can be
extended, repeatedly using the control switch in this way
until the last initiated timing period is permitted to end
and output contacts return home.
Some typical Applications: Air Conditioning, automatic
Door Controls, Lighting Controls, burglar alarms, Vending
Machines, circuits, conveyor systems, instrument control,
watchdog circuits.
REPEAT CYCLE (FLASHER)
Period begins. The contacts transfer at the end of the Off
time Delay Period and the ON time delay period begins.
At the end of the ON time delay period output contacts
return home and OFF time delay period begins again.
This sequence will continue as long as input power is
supplied to the Input Pins.
