NC contact Y1 is connected to Y2 output circuit and NC contact Y2 is connected Y1 output circuit.<br />

If Y1 is ON, Y2 will definitely be OFF and vice versa. This forms an Interlock circuit which prevents<br />

both outputs to be ON at the same time. Even if both X1 and X2 are ON, in this case only Y1 will<br />

be enabled.<br />

Example 7 - Sequential Control<br />

Connect NC contact Y2 to Y1 output circuit and<br />

NO contact Y1 to Y2 output circuit. Y1 becomes<br />

one of the conditions to turn on Y2. In addition, Y1<br />

will be OFF when Y2 is ON, which forms an<br />

sequential control process.<br />

Example 8 - Oscillating Circuit<br />

In the first scan, Y1 turns on. In the second scan, Y1 turns off due to the reversed state of contact<br />

Y1. Y1 output status changes in every scan and forms an oscillating circuit with output cycleΔ<br />

T(ON)+ΔT(OFF)<br />
