** Important:
A dry circuit switch is recommended. A “dry circuit” switch is one rated to
reliably switch currents of less than 50mA. Use of a switch rated for other than
dry circuit may result in failure of the time delay relay to function properly.
The dotted lines shown between pins on 11-pin diagram indicate internal connections.

72 & 92 - Output relay is energized at the completion of the time interval which is initiated
by the application of input voltage.
76 & 96 - Same as the above except, closing the control switch after time out will de-
energize the relay and reset the timer. Opening the switch will initiate another time interval.
Closing the control switch during timing will reset the time to zero and inhibit timing until
opened again.
76 & 96 - Output relay is energized by the closing of the control switch with the input applied
or the application of input voltage with the control switch already closed. The time interval will
be initiated by the opening of the control switch with the relay de-energizing at the completion
of the time interval. Closing the control switch after time out will energize the relay in
preparation for another time interval. Closing the control switch during timing will reset the
time to zero and inhibit timing until opened again.

72 & 92 - No Time Delay - Instantly On
76 & 96 - Output relay will energize with the application of the input voltage when the
control switch is open. Control switch closing will de-energize the relay. A timing interval will
be initiated with the opening of the control switch, at the completion of which the relay
willenergize. With the control switch closed upon application of input voltage, the relay will
wait until the control switch is opened to initiate a time interval after which the relay will
energize. Closing of the control switch during timing will reset the time to zero and inhibit
timing until opened again.
72 & 92 - Output relay is energized by the application of input voltage. The time interval is
initiated at the same time with the relay de-energizing at the completion of the time interval.
76 & 96 - Same as above. Closing the control switch will have no effect on timing or the
state of the relay.

76 & 96 - Output relay is energized by the application of input voltage with the control switch
closed or the closing of the control switch with the input applied. Immediately upon either,
timing is initiated with the relay de-energizing at the completion of the time interval. Closing the
control switch after time out will reset the timer, energize the relay, and initiate another time
interval. Closing the control switch during timing will have no effect on timing or the state of the
relay.
72 & 92 - Output relay will begin cycling at a 50% duty cycle with the application of input
power. The initial state of the relay will be de-energized.
76 & 96 - Same as the above except, closing the control switch will de-energize the relay
and inhibit timing until it is once again opened, at which time it will start from zero time.

76 & 96 - Output relay will initially be energized with the application of the input voltage when
the control switch is open. Control switch closing will de-energize the relay and start a time
interval. At the completion of the time interval, the relay will energize. With the control switch
closed upon application of input voltage, a time interval will be initiated after which the relay will
energize. Closing of the control switch during timing will have no effect on timing or the state
of the relay.
72 & 92 - Output relay will begin cycling at a 50% duty cycle with the application of input
