Example 6- Interlock control

Y1

Y2

NC contact Y1 is connected to Y2 output circuit and NC contact Y2 is connected Y1 output circuit. If Y1 is ON, Y2 will definitely be OFF and vice versa. This forms an Interlock circuit which prevents both outputs to be ON at the same time. Even if both X1 and X2 are ON, in this case only Y1 will be enabled.

Example 7 - Sequential Control

X1 X3 Y2

Y1 Y1

X2 X4 Y1

Y2 Y2

Connect NC contact Y2 to Y1 output circuit and NO contact Y1 to Y2 output circuit. Y1 becomes one of the conditions to turn on Y2. In addition, Y1 will be OFF when Y2 is ON, which forms an sequential control process.

Example 8 - Oscillating Circuit

An oscillating circuit with cycle ΔT+ΔT

Y1	Y1
	Y1

T T

In the first scan, Y1 turns on. In the second scan, Y1 turns off due to the reversed state of contact Y1. Y1 output status changes in every scan and forms an oscillating circuit with output cycleΔ T(ON)+ΔT(OFF)
