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.
Initial Dielectric Strength
Tim ing Modes
Betw een Open Contacts: 500V rms, 60 Hz.
Betw een All Other Conductors: 500V rms, 60 Hz.
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.

Input Data @ 25°C
Voltage: 24 & 120VAC and 12 through 110VDC.
Pow er Requirem ent: AC Types: Typically less than 3 VA.
DC Types: Typically less than 3 W.
Transient Protection: Yes.
Reverse Voltage Protection: Yes.
Delay on release – Input voltage must be applied continuously to operate
the internal relay. When control Input is applied, the relay energizes.
When control input is removed, timing begins. When timing is complete,
the relay will de-energize. Time may be reset to zero during timing by
reapplying control input.
