Usability was the focus in the development of the 859-477 triggered timer relay, which features a high-resolution, top-mount potentiometer. The 12-turn potentiometer augments two side-mount DIP switches that select time ranges of 0.5 to 2 seconds, 1 to 12 seconds, 5 to 90 seconds and 50 seconds to 12 minutes. The top-mount potentiometer enables users to fine-tune time delay settings without removing the 859-477 from DIN-rail.
