Control Circuit Diagram Symbols

By | August 14, 2022



Control circuit diagrams are essential for electrical professionals, who must be able to understand the circuitry of systems and machines in order to diagnose and troubleshoot issues. Understanding control circuit diagram symbols is the first step to navigating these complex systems.

A control circuit diagram symbol is an international standard that represents an electrical or electronic component within a circuit. The symbols are derived from a system called “Common Electrical Symbology Language” or CESL, which is monitored and maintained by the International Electrotechnical Commission (IEC). This system allows manufacturers and designers to quickly understand a circuit diagram as they can identify each component and its function.

Control circuit diagram symbols include transistors, resistors, switches and chips. In addition, a variety of arrows, lines and dots represent connections between components, as well as the flow of energy or data. Control circuit diagrams are also notated with symbols such as X, Y and Z, which indicate the variables used to control various components in the circuit. To ensure accuracy, traditionally control circuit diagrams have included text labels next to their symbols to indicate values, such as resistor values, switch positions, and processor operations. However, modern control circuit diagrams often use letters to indicate components, greatly simplifying the process of comprehension.

From integrated circuits to smart controllers, understanding control circuit diagram symbols is essential in diagnosing and troubleshooting electrical systems. By using this standard, engineers are able to quickly assess and solve problems. As technology advances, it is expected that the control circuit diagram will continue to evolve and offer more data in order to keep pace with the ever-evolving world of electrical engineering.
