Classic control trainer is designed with a main aim of demonstration the concept of industrial automation using components of classic control. The system is consists of two main units, first one is the system control unit which includes industrial classic control components , powering and measuring devices, digital displays in addition to three motors to be controlled. The second unit is an experimental module features an industrial automation application that consists of a centrifugal pump, 2 water tanks and control panel as an extra exercise. Using safety connecting cables trainees will be able to connect between modules for experimentation. Modular system adds more flexibility to the system making it easier and more practical to construct more and more classic control circuits using only the needed modules for the required application.

                                     
  • The trainer consists of two main units connected together to power the second unit from the main control unit using a cable.
  • First unit is the operation & control unit that includes all classic control components, while the other unit features a scaled-down industrial application that consists of a closed loop process of controlling water pressure in a tank.
  • Main unit operation module is equipped with ON/OFF switch, emergency switch, a circuit breaker & 3-phase power supply.
  • Modules for classic control components included in the main unit are:
    • Limit switch module
    • Emergency switches module
    • Push buttons module
    • Indication LEDs module
    • ON/OFF switches module
    • Selector switches module
    • 3 Pole relays module
    • Contactors module
    • Thermal overload module
    • Electronic overload module
    • Digital counter module
    • Digital pulse meter module
    • Inverter module
    • Timers module
    • Two- 3phase motors
    • Single-phase motor
  • Terminals of each module are displayed in different colors banana sockets to allow connecting between components.
  • The main unit also includes a schematic diagram of the industrial process for better understanding of the system and to help operate the process in the right sequence.
  • Modules with test points for the industrial process components are included in the control panel such as:
    • Pump module
    • Pressure switch module
    • Level electrode module
    • Solenoid valve module
    • Electrode level sensors
  • Each of the 3 electric motors provided at the main unit is equipped with a transparent cover on the rotating part to ensure system safety during training.
  • A speed sensor on each motor shaft to measure its rotating speed.
