: Los diagramas de automatización y control se diseñan preferentemente de forma vertical, donde el flujo de corriente se lee de arriba hacia abajo. 2. Tabla Comparativa de Símbolos Eléctricos Fundamentales

While the symbols for a are identical in both standards, other elements show variations:

El sistema europeo utiliza números específicos para identificar la función del contacto (ej. 13-14 para contactos normalmente abiertos, 11-12 para cerrados). El sistema americano suele utilizar letras y números combinados según el fabricante o la función del relé (ej. A1-A2 para bobinas, común en ambos pero con variaciones de terminales auxiliares).
