This creates an SFG that matches the circuit schematic. The SFG clearly shows circuit operation and can be used as a circuit description. In VSA, the voltage at each schematic node becomes an SFG node ...

With this simple circuit configuration, an optoisolator can drive a standard 2N2222 transistor output high or low to indicate if the line voltage is 120 V or 220 V ac.

Note that because there is a common portion of the winding (Section 1-2), there is no isolation between the input and output circuits. Also note that there is only one winding. As shown in the diagram ...

Output 5.12.1: Schematic Representation of Data Flow Next, a typical sequence of procedures followed at the scheduling of a nuclear power plant outage is shown using the NETDRAW procedure. Such a ...

For wiring distances over 100 feet, the VTF series output filter is recommended. Starting at $329.00, VTF series output filters combine line reactor and resistor-capacitor filter circuit to provide ...
