The product comes with multiple Part Numbers, including 776564-01, 776564-02, 776564-03, 776564-04, 776564-05, and 776564-06, catering to a wide range of requirements within the GPIB category. Specifically designed as a GPIB-120A model, this device serves as a National Instruments GPIB-120A GPIB Expander/Isolator.
Its core function is to expand the GPIB system devices limit from 15 to 28 and provide an electrically isolated interface. This is significant for systems requiring larger device networks while maintaining signal integrity and isolation. The device operates within the GPIB interface system, ensuring compatibility with GPIB standards.
One of the key features is its software requirement, which is transparent, meaning that no rewriting of the user’s application software is required. This facilitates easy integration into existing systems without the need for extensive modifications. Additionally, the cabling capability of the GPIB-120A doubles the cable limit to 40 meters, offering greater flexibility in device placement and system configuration.
It supports two busses (Bus A and Bus B), with complete isolation between them. This feature is vital for systems that require operational reliability and protection against electrical interferences. The device provides operating and breakdown isolations of 60 V and 1600 V respectively, ensuring the system’s safety and longevity.
The connector type supported by this device includes the Standard Amphenol or Cinch series 57 Microribbon or Amp Champ, which are widely used and trusted in the industry. Furthermore, the presence of seven front panel LEDs indicates the Active Controller and System Controller status, offering immediate visual feedback on the system’s operational state.
The GPIB-120A is equipped with 16 signal lines, comprising five interface management lines, three handshake lines, and eight data lines, providing comprehensive connectivity options for various GPIB system requirements.
