AGASTAT

Catalog 1308242

Issued 3-03

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.
