Figure 2-77 shows a Function Block Diagram using a TPO function block. Time Proportioning outputs are
commonly used for electrically heated applications where regulating the amount of ON time vs OFF time of
a heater is used to control temperature. In the example the TPO output is used to activate a relay output to
