Desde hace mucho tiempo estuve desarrollando un circuito\u00a0 que sea capaz de convertir se\u00f1ales de corriente variable de 4-20mA a una salida de voltaje variable para poder trabajar\u00a0 con microcontroladores o con dispositivos de nivel TTL. Cabe mencionar que este proyecto es muy \u00fatil para aplicaciones de la industria. Aparte de ello, este circuito ser\u00e1 integrado en las placas de PLC que venimos desarrollando. Es decir, para la pr\u00f3xima versi\u00f3n ya tendremos entradas de corriente (4-20mA). Efectivamente ya tenemos concluido el proyecto, as\u00ed que en este episodio aprenderemos a como realizar el circuito y tambi\u00e9n la creaci\u00f3n de la tarjeta PCB.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><\/div><\/section>
