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.
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.
Timing Specifications
Timing Ranges: OFF time and ON time ranges need not be the same.
6 to 180 cycles; 0.1 to 3 / 1 to 10 / 0.5 to 15 / 1 to 30 / 2 to
60 / 4 to 120 / 6 to 180 / 10 to 300 sec.; 0.33 to 10 / 0.5 to
15 / 1 to 30 / 2 to 60 min. (All are +10%, –1% of maximum
values).
Timing Adjustment: Two internal potentiometers with external knobs.
Accuracy: Repeat Accuracy: ± 1% ± 0.004 sec..
Overall Accuracy: ± 2.25% max.
Reset Time: 25 ms. max. (between deenergization and reenergization
without affecting accuracy.)
Relay Operate Time: 20 ms.
Relay Release Time: 15 ms.
