The ELK Products Delay Timer is designed to be an economical and flexible solution for any general-purpose timer application. The unit can be configured for use on 12 to 24V systems, with positive or negative trigger logic. Positive triggers can be as low as 4.5V. Setup is quick and easy with thumbwheel adjustment between 1 and 60 seconds. A quick jumper setting converts the time from seconds to minutes! The Timer can be configured to activate once for each trigger, or free-run as soon as power is applied. The Relay can be configured to be normally on or normally off.
