PLC basic models

The board is subdivided into four topic areas.

• Digital technology
  • To convey the basics of digital technology components without using a PLC
  • 2 AND gates each with two inputs
  • 2 OR gates each with two inputs
  • 2 Negations
  • 1 XOR with two inputs
  • 1 RS flipflop
  • 1 SR flipflop
• Traffic light control
  • T-intersection with traffic lights for pedestrians and street traffic
  • 11 LEDs to indicate traffic light signals
  • 8 2-mm input sockets for control of traffic light LEDs
  • 2 pushbuttons for simulation of press prompt at the pedestrian crosswalk
  • 1 pushbutton for simulation of the request contact on the street
  • 2 2-mm output sockets for the request signals
  • 25-pin D-Sub connector plug with connection to digital inputs and outputs of the model for quick connection to the PLC
• Sensors / actuators
  • Analog value processing by two sensors and two actuators
  • Temperature sensor with 2 mm sockets for tapping analog temperature signal
  • Light sensor with 2 mm sockets for tapping analog brightness signal
  • Lamp with 2 mm sockets for analog control of lamp brightness
  • Motor  with 2 mm sockets for analog control of motor speed
• 7 segment display
  • Two 7-segment displays
  • 6 sockets for control of the 7-segment displays
  • 1 pushbutton with socket for display activation
  • 25-pin D-Sub connector plug with connection to digital inputs and outputs of the model for quick connection to the PLC
