Example 4 - Power down latched circuit
The auxiliary relay M512 is a latched relay. Once X1 is ON, Y1
retains its status before power down and resumes after power
up.

Example 5 - Conditional Control
Because NO contact Y1 is connected to the circuit of Y2 output, Y1 becomes one of the conditions
for enabling Y2, i.e. for turning on Y2, Y1 has to be ON
Example 6- Interlock control
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
Example 7 - Sequential Control
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.
