Cam timers from ATC are compact and economical motor-driven timers. 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. 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.
