The Timing Relay Functions Tool is a learning tool that visually demonstrates ten of the most common timing functions available on time delay relays. This tool is designed to help installers choose the correct timing function to fit their application.

Users select a type of trigger (power or switch), choose from the available timing functions and then apply power on the interactive wiring diagram. The wiring diagram and timing chart will demonstrate how the selected function works.

Available functions include:
• Interval
• Off delay
• On delay
• On and off delay
• Pulse generator
• Retriggerable interval
• Single shot
• Symmetrical repeat cycle: starting closed
• Symmetrical repeat cycle: starting open
• True off delay
