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.
Contact Data @ 25°C
Tim ing Modes
Arrangem ents: 2 Form C (DPDT).
Material: Silver-cadmium oxide alloy.
Rating: 10A @ 30VDC or 277VAC, resistive; 1/2 HP @ 250VAC; 1/3 HP @
120VAC.
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.

Initial Dielectric Strength
Betw een Open Contacts: 500V rms, 60 Hz.
Betw een All Other Conductors: 500V rms, 60 Hz.
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 through 240VAC and 24VDC.

DC Types: Typically less than 3 W.

Interval on – 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.

* If control switch is closed when power is applied, relay will immediately energize. A 50 millisecond minimum switch closure is required. IMPORTANT: A dry circuit switch is recommended.
“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.
** Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”.
