Continuous Cycling Timer CircuitItem # item-1850

System pressure is turned on. Air flows through port 2 of Timer #2 to drive timer #1 and to operate the air pilot valve turning on air to the device being controlled. When timer 1 reaches set time, it sends a signal to port C of timer 2,shutting down the air supply to the air piloted valve and timer 1. This enables timer 2 to begin timing. When timer 2 reaches set time, it operates and the cycle is repeated. Removing the air supply resets the circuit to the start position.

One On Delay PT timer and one Off Delay PT timer with the required time ranges.
Single air piloted, spring return valve, 3 way, cat. no. 75026-71-21 (1/8), 75046-71-21 (1/4), 75066-81-21 (1/2). For operating double acting cylinders use 4 way valves.
