Technical manual
Requirements for the PLC:
  • 12 digital inputs
  • 1 analog input (The level of voltage is adjustable)
  • 8 relay output
  • It should fit into a standard power switch rail.
  • The cutting should be 130mm wide and 95 mm deep.
  • Functional voltage: 24V
  • Accepted electricity: maximum 200mA (Excluding the PLC’s demand on electricity)
Physical structure:
  • The case is made of 4mm plexiglass.
  • The bottom is taped with abrasion-resistant stickers. The case is held together by aluminium profile, which is high quality. It is 2.4 mm thick, with protection on the edges.
  • External sizes: width: 545mm, depth: 317mm, height: 75mm (The height refers to the distance between the bottom and the profile, an extra 10mm should be counted for the buttons or 35mm for the PLC)
  • The PLC’s input voltage is 0/24V, low level: approximately 1V, high level: 22V
  • The PLC’s outputs deliver a 5V voltage.
  • The electricity, flowing through the relay is not reaching 50mA.

The parameters of the functionalities of the „card-edge” connector, are in the downloads section.

  • 4 LEDs (8mm)
  • 3 buttons
  • 1 switch

    The buttons lock on press. The colors of the buttons and switches match with the colors of the LEDs above them.

  • 4 LED (8mm)
  • 4 buttons
  • The arrengement of the LEDs form a four levels stairway.
  • 4 response buttons
  • The PLC controls a PCB disk, which can be moved up- and down, modelling an elevator. The buttons of the cabin are simbolized by 4 micro switches.
  • The arrival of the elevator is monitored by 4 infra sensores, which, after analyzing the signals, sends a digital signal to the PLC.
  • The mechanics are made of 4mm of plexiglass. The elevator is bend by a 12V stepper motor, which is located in the top section. The disks that are spinning the string, are made with roller-bearings.
  • The signals of buttons of the cabin are detected by a bronze interface and after evaluation, they are forwarded to the PLC.
  • The movement of the cabin is monitored by a software which returns upper and lower end points.of cabin state.
  • In case of overunning, the system triggers a sound signal and stops the motor, regardless of the PLC. The mechanics can stand accidental stops without any failures.
  • In case of false control, it triggers an alarm sound.
  • 4 buttons
  • 3 5mm LED
  • A 250 mm long and 40 mm wide conveyor belt, which can be moved to the left and to the right.
  • 4 infra sensors, which, after evaluation, sends a digital signal to the PLC.
  • The sensors are located 20 and 40 mm away from the edges. The mechanism is made of a 4mm plexiglass.
  • The belt is a 1 mm thick „ribbed belt”.
  • The drums, that are responsible for the rotation, are rotated by 2 stepper motors. They are made with roller bearings.
  • 4 buttons
  • 3 LED (5mm)
  • The modell drives a flywheel with the help of a 24V DC motor. The rotation of the disc is monitored by the system and, in case of failure, an alarm signal is triggered.
  • 2 orange LEDs are responsible for the feedback of the current function (whetcher it is in delta or star mode).
  • 3 buttons (towards the PLC)
  • 3 LEDs (5mm) (from the PLC)
  • The mechanism is made of a 4mm wide plexiglass. The moving part is made of a 4mm wide plexiglass with a special sticker on it’s surface.
  • The lifting is controlled by a 5V, high transmission stepper motor, downwards it uses gravity. The current position is defined by the system which is counting the steps of the stepper motor. Therefore the end point switch determines the starting position. The analog input of the PLC is created by the controller, which, leaves via a booster. This booster’s fortification can be set with a potentiometer.
  • It has feedback LEDs, yellow: loading in progress, red: overloading (sound signal too)
