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 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. Power Requirement: 3W, max. Transient Protection: Non-repetitive transients of the following magnitudes will not cause spurious operation of affect function and accuracy.
