Description
The National Instruments GPIB-120A GPIB Expander/Isolator is a crucial component designed to enhance the functionality of GPIB systems. With part numbers ranging from 776564-01 to 776564-06, this device falls under the category of GPIB and is specifically modeled as GPIB-120A. It serves a pivotal role in expanding the GPIB system devices limit from the standard 15 to an impressive 28, alongside providing an electrically isolated interface for enhanced safety and performance.
One of the key features of the GPIB-120A is its ability to double the cable limit to 40 meters, significantly extending the reach and flexibility of GPIB system configurations. This is particularly beneficial in complex laboratory setups or industrial environments where extended connectivity is essential. The device operates with a transparent software interface, eliminating the need for users to rewrite their application software, thereby ensuring seamless integration and operation within existing GPIB systems.
The GPIB-120A is characterized by its sophisticated bus configuration, which comprises two busses (Bus A and Bus B). Each bus possesses identical circuitry and operates in complete isolation from the other, thereby enhancing the system’s reliability and reducing the risk of data corruption. The device boasts operating and breakdown isolations of 60 V and 1600 V respectively, ensuring robust protection against electrical interferences and surges.
Concerning physical connectivity, the GPIB-120A accommodates a variety of connector types, including Amphenol or Cinch series 57 Microribbon or Amp Champ type connectors. This flexibility facilitates easy and secure connections to a wide range of GPIB devices. Additionally, the device is equipped with seven LEDs that provide visual indications of the Active Controller, System Controller, among other crucial operational statuses, allowing for easy monitoring and troubleshooting of the GPIB network.
The GPIB-120A also handles 16 signal lines, which include 5 interface management lines, 3 handshake lines, and 8 data lines, providing comprehensive coverage for the various signal requirements within a GPIB system. This ensures that the device can support a broad spectrum of GPIB communications and functionalities, making it an indispensable
