Abstract

Circuito universal de entrada/salida para sistema de microcalculador que incluye un microprocesador, una línea común universal de entrada/salida, un primer dispositivo para acoplar dicho circuito con dicha línea común de entrada/salida, y un segundo dispositivo para acoplar dicho circuito con terminales de campo donde una señal analógica o digital de entrada o de salida ha de ser tratada, siendo dicho circuito de entrada/salida capaz de funcionar como circuito analógico o digital de entrada o de salida de acuerdo con las conexiones de campo, caracterizado porque dicho circuito de entrada/salida incluye un transistor conectado en serie con una resistencia, un convertidor analógico/digital acoplado entre dicha resistencia y dicha línea común de entrada/salida para proporcionar señales de realimentación a dicho procesador para finalidades de supervisión, y un dispositivo que responde a las señales de salida del calculador para excitar dicho transistor de modo que funcione en diferentes condiciones según la función que se desea que realice dicho circuito de entrada/salida.
