Specification Grade Repeat Cycle

Catalog 1308242
Issued 3-03
AGASTAT
SRC
series
Specification Grade Repeat Cycle
Plug-in Time Delay Relay
Repeat Cycle timing mode
Dual knobs for user adjustment of on and off times.
13 timing ranges from 0.1 sec. to 60 min.
10A DPDT output contacts
Exceptional immunity to line transients and noise
Premium components enhance reliability
Superior reset time of 24 msec.
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 Modes
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.
Input Data @ 25°C
Voltage:
See Ordering Information section for details.
Power Requirement:
3W, max.
Transient Protection:
Non-repetitive transients of the following magni-
tudes will not cause spurious operation of affect function and accuracy.
