File E22575 File LR15734 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 Timing Modes Between Open Contacts: 500V rms, 60 Hz. Delay on operate Delay period begins when input voltage is applied. At Between All Other Conductors: 500V rms, 60 Hz. 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 ON VOLTAGE OFF N.O. RELAY ON TIME CONTACTS OFF Input Data 25C Voltage: 24 & 120VAC and 12 through 110VDC. Delay on release Input voltage must be applied continuously to operate Power Requirement: AC Types: Typically less than 3 VA. the internal relay. When control Input is applied, the relay energizes. DC Types: Typically less than 3 W. When control input is removed, timing begins. When timing is complete, Transient Protection: Yes. the relay will de-energize. Time may be reset to zero during timing by Reverse Voltage Protection: Yes. reapplying control input.
