Percentage Cycle Timers

This timer provides repetitive cycling for fans, misters, foggers, feeders, process equipment, oil pumps, irrigation, nurseries and other short cycle applications. The timer is field adjustable for a percentage of a total cycle duration. Total cycle durations can be set from 30 seconds up to a maximum of 30 minutes, with ON/OFF durations from 1 second up to 29 minutes. The total cycle duration is selected by positioning two jumpers on the circuit board, which are factory preset for 10 minutes. The percentage of total ON time is selected using the rotary knob, which provides 30 separate detent positions for precise selection. Power input may be any standard 120 volt or 240 volt AC supply. The timer enclosure includes two slotted mounting holes on 5" centers and a 1/2" knockout for conduit connection.

This timer is designed to function in dusty, ammonia and wash-down environments. It has an environmental operating temperature range of -10°C (14°F) to +60°C (140°F) and will withstand up to 6000 volt 3000 amp power surges.
