The Allen-Bradley 596-TL33 Pneumatic Timer Off-Delay is a timer attachment kit that adds a left-hand, pneumatic off-delay timing function to 500L-series contactors and starters. Designed for sizes 0 through 5, it provides one normally open and one normally closed contact to support the off-delay operation in the control circuit. This accessory uses pneumatic timing—relying on compressed air to keep the output energized for a defined delay after the input is released—so no additional electronics are required for the delay function. A right-hand version exists as the 596-TR33 for alternate mounting.
