EB-116 Position Control and Stepper Motor
The EB-116 is a single hoard comprehensive instructional module
designed to teach basic concepts of position sensors to technology
students. The module can be operated as a stand-alone unit or integrated
to the newly developed EB-2000 Computer Managed Laboratory.
The module contains experimental circuits with which the student
performs a number of conceptual experiments at various levels of
difficulty. Manual or computer driver fault-finding exercises and
testing are available when the module is interconnected to the SB-
2000 sys tern, providing valuable experience in the training and
diagnosis of faults. Test equipment, when used, attaches to the
board via 2mm jacks, placed at various points around the circuits.
Students are required to do only a minimal amount of wiring so training
time is maximised. A comprehensive student manual is provided with
each training module. The manua1 correlates to the exercises to
convey concepts relating to the technologies covered, allowing focus
on specific performance objectives.
Description
The EB-116 module is designed so students will spend the maximum
time on the experiments and practice drills for testing comprehension
and troubleshooting. The module also ensures that students use their
time more efficiently. The printed circuit boards are pre-wired
so that set-up time is minimal. For operation the module is connected
to a PUZ-2000. To facilitate the exercises, all the major signals
are brought out on-board with 2mm jacks for tests and interconnections.
The ICs and the transistors are mounted on sockets, enabling easy
replacement. The student has only to plug-in the appropriate patching
cords and shorting plugs in order to perform the recommended experiments.
The boards also come equipped with "black boxes" containing
components used in the fault-finding and practice modes, components
which should not be visually identified by the trainee.
