Standard electrical IEC symbols also known as IEC 60617 (British Standard BS 3939) used to represent various devices including pilot lights, relays, timers and switches for usage in electrical schematic diagrams

relay. Contactors appear nearly identical to relays on schematic diagrams. Some manufacturers employ contactors that use a single set of contacts. A “bus bar” is placed over the connection where the other set would be, as shown in Figure 6. Figure 16 at the end of this chapter includes many other symbols for switches and relays. THE BASIC ...

One other alternative is to use logic diagrams on the elementary wiring diagram. Logic diagrams are a graphical display that shows what is happening in the logic of the relay or communications system. Go back to contents ↑ DC Schematics and IEC 61850 Station Bus

The same evolution in protective relay logic also increased the importance of having a method of detecting the basic overall logic on one diagram. Prior to the user defined logic in microprocessor based relays, the control schematic provided this overall logic diagram because the logic was created by the wiring of individual functions together.

Supports IEC 61850 Editions 1 and 2, including HSR and PRP, GOOSE messaging and IEC 61850-9-2 LE for less wiring and supervised communication; IEEE 1588 V2 for high-accuracy time synchronization and maximum benefit of substation-level Ethernet communication; Supports Modbus, DNP3 and IEC 60870-5-103 communication protocols
