Ideal for digital logic circuit design and
experimentation
Compact design for easy storage
Includes built-in Clock, Pulsers and Logic Switches
and Logic Indicators
Selectable TTL or CMOS operating voltages
Triple output power supply
Premium breadboarding area with 8 power rails
3-year warranty on all parts and workmanship.
The PB-502 Advanced Logic Design Trainer is
a portable robust instrument capable of
satisfying many requirements arising in the
design and study of digital logic circuitry. The
PB-502’s selectable operating voltage further
aids its versatility by allowing the trainer to be
used in either TTL or CMOS operating mode,
The trainer contains three integral power
supplies and input/output devices that
simplify the construction of a wide range of
circuits. Typical circuits that can be built on
the PB-502 include, operational amplifiers,
comparators, A to D converters, gates and
counters. The PB-502 can also interface
directly to a microprocessor. The PB-502 is
housed in a tough, molded plastic carrying
case with an integral hinged cover which
stacks neatly for storage. Utilizing the PB-
502, students will learn valuable hands-on
breadboarding techniques and build a solid
foundation in digital logic circuit
experimentation, construction and analysis.
Global Specialties trainers provide the most
complete platform required to enable
engineers and technicians to train for careers
in the rapidly growing field of electronics
technology.
Use the PB-502 to
construct a wide variety
of experiments, including
but not limited to:
Logic Gates & Boolean
