E500

This model is an ON delay control. Timing begins when the control is energized. Operation of the load is delayed for the time set on the dial. The ON delay is used for staggering motor loads such as gas oven pre-purge applications, regrigeration compressor delays, and process sequences where a delayed start switch is needed.

Timing range: 5 seconds to 3 hours 

E501

This model is an interval control. The load and timing cycle begins when the control start switch is energized. At the end of the timing cycle, the load shuts down with the switch in the normally open position. The E501 is great for timing many industrial processes.

Timing range: 10 seconds to 12 hours 

E502

This model is an OFF delay control. The timing cycle begins when the control switch is activated. At the end of the timing cycle, the load shuts down. The OFF delay is used when 2 loads start simultaneously but 1 must shut down after the other . This timer is ideal for post-purge of gas ovens, exhaust fans used for processes involving noxious fumes, and public restroom fan control.

Timing range: 5 seconds to 3 hours 

E501-M

All models (shown here as E501-M) available as "M" mechanism without NEMA 4X enclosure backing.
