calibrated in seconds ±5%.
Sockets: Models with 8-pin base fit either 27E122 or 27E891 (snap-on)
screw terminal sockets. 11-pin types fit either 27E123 or
27E892 (snap-on) screw terminal sockets.
Weight: 8 oz. (227g) approximately.
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 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.

* If control input is applied when supply input is applied, relay will immediately energize. A 50 millisecond minimum control pulse is required.
** Note Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”.
