Data store programmed control circuit with PIC-microcontroller for LED display or machine control has circuit board with sockets for control modules

摘要

The SPS (speicherprogrammierbare Steuerung) has several components including microcontrollers, drive building blocks (IC2-5) and a network of resistors arranged on a circuit board. The circuit board has 32 digital inputs or outputs (K1-12) and there is a microcontroller (IC1) in the middle of the board, of type PIC16F877- DIL40. -
