A compact and economical motor-driven cam timer, the 324C precisely controls one to twelve load circuits through easily-set screwdriver-adjustable cams. Each timer provides a wide range of cycle times through a set of interchangeable gears.
Easy and Precise Cam Adjustment: With ATC’s unique split-cam design, each side of the cam is separately screwdriver-adjustable in either direction: either side determines the precise instant during the cycle when the switch will actuate, the other side determines how long the switch will remain actuated. Adjustments are easy and precise: 1/4 turn of the adjusting screw equals 0.5% of cycle time. A setting disc, calibrated in 1% increments, facilitates program set-up and indicates cycle progress.
One to Twelve Precision Switches: Whether used as a time or sequence programmer, the 324C can be ordered with any number of cam-operated switches from one to twelve. Each SPDT precision switch is rated at 10 amps, 120 VAC and is 1/3 hp rated at 120 or 240 VAC.
Wide Range of Cycle Times: The 324C is available with a choice of 14 synchronous motors that provide more than 270 cycle times between 3 sec and 60 hrs. Each motor provides an adjustable range of 21 cycle times, with a ratio of over 2.5:1, through a set of interchangeable gears. Changing gears is a simple operation that takes only a few minutes.
Accuracy: The repeat accuracy and setting accuracy of the 324C are both within ± 0.25%. Follower fingers precisely track the contour of the cams, accurately operating the precision switches with quick-break and action.
Sequence Control: The 324C can be ordered without a motor and with a 1 inch long shaft extension on either or both ends, for use as a rotary cam limit switch.
