PB-502: Portable Advanced Logic Design Trainer

 

The PB-502 is a 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 cases with an integral hinged cover which stacks neatly for storage. 

MSRP: $275.00
