Initial Dielectric Strength

Between Open Contacts: 500V rms, 60 Hz.

Between All Other Conductors: 500V rms, 60 Hz.

Timing Modes

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.

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.

Interval on (without control switch) – 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.

Interval on (with control switch) – 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

reclosing the control switch.

* 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. 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.

** Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”.
