Abstract

Un sistema (10) di pilotaggio di carichi preferibilmente utilizza un dispositivo di controllo a microprocessore (20) per generare segnali di scrittura/lettura e segnali di comando ricevuti da un circuito nei terminali di ingresso di scrittura/lettura e di comando/stato (16, 17). Il circuito (15) risponde ai segnali di ingresso e controlla un interruttore a semiconduttore (11) che comanda lo stato di funzionamento di un carico (14). Il circuito (15) comprende un rivelatore di stato alto (28) cortocircuitato al carico, un rivelatore di stato basso (29) cortocircuitato al carico ed un rivelatore di apertura di carico (30) i quali vengono usati per rivelare vari malfunzionamenti e forniscono una predeterminata sequenza di stati logici sul terminale di ingresso di comando/stato (17) durante i cicli di lettura implementati dal dispositivo di controllo (20). Perciò, una linea di ingresso (terminale 17) viene usata sia per trasmettere i comandi all'interruttore a semiconduttore (11) sia per ricevere o una sequenza di stati logici indicativi di vari modi di malfunzionamento. Ciò permette al dispositivo di controllo di determinare quale
