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.
Timing Mode
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.
