Allen-Bradley 709-AOD Coil

Allen-Bradley 709-AOD U coil is the energizing coil for a Bulletin 709 motor starter, Size 0, featuring a 120 VAC control coil. It is designed to be wired into a standard control circuit to energize the starter and close its power contacts when the control voltage is applied. This 120 V AC coil variant is associated with the 709 family and is compatible with legacy Allen-Bradley 709 starters used in industrial panels, typically operated in 50/60 Hz environments. According to distributor listings, the 709-AOD coil is discontinued by the manufacturer, with available stock usually sourced as refurbished or surplus units. The coil is commonly referenced as the U coil variant for 120 VAC operation and is encountered in restoration or maintenance projects involving vintage Allen-Bradley equipment.
