Module System Digital Technology (Series 9400)

The Module System Digital Technology Series 9400 is a modular training system for the fundamentals of digital technology and microcomputer technology. Only the modules required for a given experiment are plugged in, which keeps the setup clear and reduces preparation time.

  • Modular training system for digital technology and microcomputer technology
  • 25 digital modules from Type 9401 to 9425
  • Use with UNIVERSAL BOARD 1, UNIVERSAL BOARD 2 and the DIGI MODULE BOARD
  • Central +5 V DC module supply via the 4 mm plug system
  • DIGI MODULE BOARD with built-in power supply, input and output units
  • Storage plate and box version for transport and storage

Application and system concept

The Module System Digital Technology was developed to teach and deepen fundamental knowledge in digital technology, contactless control technology and microcomputer technology.

It consists of plug-in modules that are inserted into the boards or base plates depending on the experiment. This keeps the setup clear and allows quick adaptation to the task at hand.

Modules and board variants

The system includes 25 digital modules ranging from the clock generator and keyboard to ALU, memory and A/D-D/A converter modules.

The setup options include UNIVERSAL BOARD 1 (Type 8175), UNIVERSAL BOARD 2 (Type 8176), universal base plates (Types 1012.1 and 1012.2) and the DIGI MODULE BOARD (Type 3930).

The DIGI MODULE BOARD integrates the power supply, keyboard, clock generator, LED display, 7-segment display and adapter field for direct laboratory use.

  • Clock generator Type 9401
  • Keyboard Type 9402
  • OR/AND gates Type 9403
  • Hex / dual code switch, push-button, signal source Type 9404
  • Multiplexer / demultiplexer Type 9410
  • D flip-flop Type 9411
  • ALU Type 9419
  • 7-segment display Type 9423
  • Adapter Type 9425

Manual and extensions

The system is accompanied by the manual 'Experiments in Digital Technology' Type V 0160, which contains the experiment descriptions with tasks and solutions.

Additional items include the accessory set Type 3910.1, the storage plate Type 3930.10 and the box Type 3930.20.
