Abstract :
A newly fabricated multiplex output circuit (output interface circuit system) was connected to the PIO of an 8-bit single-board microcomputer. Using this the system more than eight actuators can be operated. In order to avoid conduction noise induced in this system, the Z80 microcomputer is isolated from actuators such as rotatory solenoids by using photocouplers between them
