The PID Board was specially developed for basic and advanced experiments in control technology.
- Universal training device for control engineering
- Built-in power supply (short-circuit proof)
- All basic experiments possible without storage oscilloscope
- Built-in pre-trigger circuit guarantees complete representation of the signal
- As a test object in computer-aided teaching
Note: The matching experiment instructions must be ordered separately.
Our products are designed for the European market and meet CE requirements. For international use, regional regulations apply which must be observed. The usability of the products shown must therefore be checked in advance.
For each controller, the characteristic values can be adjusted over a wide range via plugs and potentiometers. The polarity of the signals can be adapted to the requirements of the overall circuit or the wishes of the trainer by means of various summing, comparison and inverting elements.
Limit indicators at the output of the controllers clearly indicate when the range has been exceeded by means of light-emitting diodes. For the electronic simulation of controlled systems, an I element, several delay elements and P elements are available. With a few exceptions, all control loop elements with time-dependent behaviour are designed in such a way that their step response can be measured with a normal oscilloscope and storage oscilloscope as well as with a Y-t recorder.
For operation with an oscilloscope, repetition frequencies up to approx. 100 Hz are possible. Measurements with a recorder can be performed as a one-time process at times in the seconds range. The decisive factor for the reproducibility and convenience of the measurements is the sequence control, which was specially developed for this board. When using an oscilloscope, this control allows the measurement process to be repeated cyclically, with all capacitors involved being discharged before each cycle. A pre-trigger circuit ensures that the signal is optimally displayed on the oscilloscope. For measurements with a recorder, each can be triggered individually. To control the recorder spring, the trigger output is available in conjunction with a relay. Via an additional RESET input, the sequence control can also be controlled by a computer or PLC.
To conduct out experiments, the board is placed on the table or hung in an A4 experiment rack for demonstration purposes. The training board is also available in a box (see "Matching this").
