GPIB-120A

Description

The National Instruments GPIB-120A GPIB Expander/Isolator is a versatile device designed to increase the device limit on GPIB systems from 15 to 28, providing compatibility with the IEEE 488.1 standard. This expansion capability is crucial for larger systems that require more devices than the standard allows. With part numbers ranging from 776564-01 to 776564-06, this expander/isolator ensures that users have a range of options for their specific setup requirements.

One of the key features of the GPIB-120A is its electrical isolation, offering an operating isolation voltage of 60 V and a high breakdown voltage of 1600 V, which is essential for maintaining system integrity and safety. The device is fitted with durable Amphenol or Cinch series 57 Microribbon or Amp Champ type connectors, ensuring reliable and consistent connections.

The front panel of the GPIB-120A is equipped with seven LEDs that provide immediate visual feedback on the Active Controller and System Controller states, along with other operational indicators. This immediate feedback is invaluable for troubleshooting and monitoring the system’s status. Moreover, the unit’s bus configuration consists of two isolated busses, Bus A and Bus B, which operate independently, allowing for flexible system expansion and enhanced isolation.

With 16 signal lines split into five interface management lines, three handshake lines, and eight data lines, along with eight shield drain or ground return lines, the GPIB-120A is designed to handle complex communication requirements efficiently. The power requirements are modest, with a typical consumption of 27 VA, and the device is designed to minimize data transfer rate degradation, with only 250 ns per byte of typical degradation, which ensures rapid communication across the system.
