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.
Tim ing Modes
Input Data @ 25°C
Repeat Cycle: Application of line voltage starts the pre-set OFF-time period
Upon expiration of the period, the output relay is energized, its contacts
transfer, and the pre-set ON-time period begins. At the end of this period
the output relay is deenergized, and a new cycle begins. The OFF and ON
cycles continue until power is removed. To reset the timer, input voltage
must be removed for at least 25 ms.
Voltage: See Ordering Information section for details.
Pow er Requirem ent: 3W, max.
Transient Protection: Non-repetitive transients of the following magni-
tudes will not cause spurious operation of affect function and accuracy.
