Users should thoroughly review the technical data before selecting a product part
number. It is recommended that user also seek out the pertinent approvals files of
the agencies/laboratories and review them to ensure the product meets the
requirements for a given application.
Tim ing Modes
Contact Data @ 25°C
Delay on operate – Delay period begins when input voltage is applied. At
the end of the delay period, the relay will operate and will not release until
input voltage is removed. Reset occurs when input voltage is reapplied.
Arrangem ents: 2 Form C (DPDT), except 8-pin delay on release model
has 1 Form C (SPDT).
Material: Silver-cadmium oxide alloy.
Rating: 10A @ 30VDC or 277VAC, resistive; 1/2 HP @ 250VAC;
1/3 HP @ 120VAC.
Expected Mechanical Life: 10 million operations.
Expected Electrical Life: 100,000 operations, min., at rated load.

TIME
Delay on release – Input voltage must be applied continuously to operate
the internal relay. When the control switch is closed, the relay energizes.
When the control switch is opened, timing begins. When timing is
complete, the relay will de-energize. Time may be reset to zero during
timing by closing the control switch.

Input Data @ 25°C
Voltage: 24 and 120VAC, and 12 and 24VDC.
Pow er Requirem ent: AC Types: Typically less than 3 VA.
DC Types: Typically less than 3 W.
Interval on (w ithout control sw itch) – The relay energizes and timing
begins when input voltage is applied. At the end of the time delay period
the relay will de-energize. Reset is accomplished by removing, then
reapplying, the input voltage.
Transient Protection: Yes.
Reverse Voltage Protection: Yes.

Interval on (w ith control sw itch) – Input voltage must be applied
continuously to operate the internal relay. The relay energizes and timing
begins when the external switch is closed. At the end of the time delay
period the relay will de-energize. Reset is accomplished by opening and
