324C Precision Switch Cam Programmer

A compact, motor-driven cam timer, the 324C serves as a multipulse repeat cycle timer, precisely controlling one to twelve load circuits through easily-set screwdriver-adjustable cams. Each timer provides a broad range of cycle times suitable for multipulse repeat cycle operation through a set of interchangeable gears. Easy and Precise Cam Adjustment: ATC’s unique split-cam design allows for each side of the cam to be separately screwdriver-adjustable in either direction: one side determines the precise instant during the cycle when the switch will actuate for a multipulse repeat cycle; the other side sets the duration of actuation. Adjustments are exact: 1/4 turn of the screw equals 0.5% of the cycle time. A setting disc, calibrated in 1% increments, facilitates program set-up and cycle progress indication. One to Twelve Precision Switches: As a time or sequence programmer and multipulse repeat cycle timer, the 324C can be fitted with one to twelve cam-operated switches. Each SPDT precision switch can handle 10 amps at 120 VAC and has a 1/3 hp rating at 120 or 240 VAC. Wide Range of Cycle Times: The 324C offers a choice of synchronous motors for various timing ranges, each motor providing an adjustable range of 21 cycle times with a ratio of over 2.5:1, through interchangeable gears. Gear changes are straightforward and quick. Accuracy: The repeat and setting accuracy of the 324C as a multipulse repeat cycle timer are both within ± 0.25%. Sequence Control: For use as a rotary cam limit switch, the 324C can be ordered without a motor and with a 1-inch long shaft extension on either or both ends. APPROVALS: File No. E24305, LR26970.
